Introduction
Chemokine (C-X-C motif) ligand 11 (CXCL11) is a small cytokine belonging to the CXC chemokine family that is also called Interferon-inducible T-cell alpha chemoattractant (I-TAC) and Interferon-gamma-inducible protein 9 (IP-9). It is highly expressed in peripheral blood leukocytes, pancreas and liver, with moderate levels in thymus, spleen and lung and low expression levels were in small intestine, placenta and prostate. Gene expression of CXCL11 is strongly induced by IFN-g and IFN-b, and weakly induced by IFN-a. This chemokine elicits its effects on its target cells by interacting with the cell surface chemokine receptor CXCR3, with a higher affinity than do the other ligands for this receptor, CXCL9 and CXCL10. CXCL11 is chemotactic for activated T cells. Its gene is located on human chromosome 4 along with many other members of the CXC chemokine family.

Introduction
REG protein was shown to be stimulated during the regeneration of pancreatic islets. Since then, many Reg-related proteins have been identified in humans and other animals. In human, the four REG family genes, i.e., REG 1 alpha, REG 1 beta, REG-related sequence (RS) and HIP/PAP, have so far been isolated. These Reg-related proteins are classified into four subfamilies according to their amino-acid sequences, but they share a similar structure and physiological function. Reg protein is a growth factor for pancreatic beta cells and also suggests that the administration of Reg protein could be used as another therapeutic approach for diabetes mellitus. Human REG cDNA which encodes a 166-amino acid protein with a 22-amino acid signal peptide. The amino acid sequence of human REG protein has 68% homology to that of rat Reg protein.
Reg I was found to be expressed mainly in pancreatic beta and acinoductular cells as well as gastric fundic enterochromaffin-like (ECL) cells. Reg I production in ECL cells is stimulated by gastrin, as well as by the proinflammatory cytokine, cytokine-induced neutrophil chemoattractant (CINC)-2Beta. In patients with chronic hypergastrinemia, Reg production is stimulated, with the increased proliferation of gastric mucosal cells. Patients with Helicobacter pylori infection also showed increased Reg production in the gastric mucosa, partly via increased plasma gastrin concentration and partly via increased proinflammatory cytokine production. The serum concentration of the reg-protein was significantly higher in patients with various pancreatic diseases than in normal controls, and was also significantly higher in patients with acute pancreatitis or chronic relapsing pancreatitis than in patients with chronic pancreatitis. Furthermore, the serum PSP/reg-protein concentration was also significantly increased in liver cirrhosis, choledocholithiasis, and various cancers of the digestive system.

Introduction
SDF-1 (stromal cell-derived factor-1) is small cytokine belonging to the chemokine family that is officially designated Chemokine (C-X-C motif) ligand 12 (CXCL12). It is produced in two forms, SDF-1?/CXCL12a and SDF-1?/CXCL12b, by alternate splicing of the same gene. Chemokines are characterized by the presence of four conserved cysteines, which form two disulfide bonds. The CXCL12 proteins belong to the group of CXC chemokines, whose initial pair of cysteines are separated by one intervening amino acid. CXCL12 is strongly chemotactic for lymphocytes and has been implicated as an important cell co-ordinator during development. During embryogenesis it directs the migration of hematopoietic cells from foetal liver to bone marrow. Mice which were knocked-out for CXCL12 gene were lethal before the birth or within just 1 hour of life. As another role, CXCL12a alters also the electrophysiology of neurons. CXCL12 was shown to be expressend in many tissues in mice (including brain, thymus, heart, lung, liver, kidney, spleen and bone marrow).
The receptor for this chemokine is CXCR4, which was previously called fusin. This CXCL12-CXCR4 interaction used to be considered exclusive (unlike for other chemokines and their receptors), but recently it was suggested that CXCL12 is also bound by CXCR7 receptor.
The gene for CXCL12 is located on human chromosome 10. In human and mouse both CXCL12 and CXCR4 show high identity of sequence: 99% and 90%, respectively.
Synonyms
SDF-1, CXCL12, Pre-B cell growth-stimulating factor, PBSF, hIRH, chemokine (C-X-C motif) ligand 12, SDF1, SDF1B, TPAR1, SCYB12, SDF-1b, TLSF-b.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized SDF-1b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL12 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized Stromal Cell-Derived Factor-1b in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Lys-Pro-Val-Ser-Leu.
Protein content
Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 1.06 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of SDF-1b as a Reference Standard.

Introduction
Chloride intracellular channel 4 (CLIC4) belongs to the p64 family; CLIC4 is expressed in various tissues and exhibits an intracellular vesicular pattern in Panc-1 cells (pancreatic cancer cells). CLIC4 is a 253 amino acid single-pass membrane protein which localizes to both the nucleus and the cytoplasm and contains one GST C-terminal domain. CLIC4 acts as a monomer which is able to form selective ion channels in target proteins, thus facilitating the transport of chloride and other ions. CLIC4 is believed to have a role in apoptosis and is able to translocate to the nucleus under stress conditions.

More Info

Introduction
Human CCL16, also called HCC-4, liver-expressed chemokine (LEC), and lymphocyte and monocyte chemoattractant (LMC), is a novel CC chemokine recognized by bioinformatics. NCC-4 cDNA encodes a 120 amino acids along with a 23 amino acids signal peptide that is cleaved to generate 97 amino acid protein. HCC4 is vaguely related to other CC chemokines, showing less than 30% sequence identity. Among CC chemokines, CCL-16 has the largest similarity to HCC-1. 2 potential polyadenylation signals are present on the human HCC-4 gene, and as a result, 2 transcripts containing roughly 1,500 base pairs and 500 base pairs have been detected. HCC-4 is expressed weakly by some lymphocytes, including NK cells, T cells, and some T cell clones. The expression of HCC-4 in monocytes is greatly upregulated in the presence of IL-10.
CCL16 shows chemotactic activity for lymphocytes and monocytes rather than to neutrophils. NCC-4 has potent myelosuppressive activity, suppresses proliferation of myeloid progenitor cells. CCL16 demonstrates chemotactic activity for monocytes and thp-1 monocytes, rather than for resting lymphocytes and neutrophils. HCC-4 induces a calcium flux in thp-1 cells that desensitized prior to the expression of rantes.

More Info

Introduction
SDF-1 (stromal cell-derived factor-1) is small cytokine belonging to the chemokine family that is officially designated Chemokine (C-X-C motif) ligand 12 (CXCL12). It is produced in two forms, SDF-1?/CXCL12a and SDF-1?/CXCL12b, by alternate splicing of the same gene. Chemokines are characterized by the presence of four conserved cysteines, which form two disulfide bonds. The CXCL12 proteins belong to the group of CXC chemokines, whose initial pair of cysteines are separated by one intervening amino acid. CXCL12 is strongly chemotactic for lymphocytes and has been implicated as an important cell co-ordinator during development. During embryogenesis it directs the migration of hematopoietic cells from foetal liver to bone marrow. Mice which were knocked-out for CXCL12 gene were lethal before the birth or within just 1 hour of life. As another role, CXCL12a alters also the electrophysiology of neurons. CXCL12 was shown to be expressend in many tissues in mice (including brain, thymus, heart, lung, liver, kidney, spleen and bone marrow).
The receptor for this chemokine is CXCR4, which was previously called fusin. This CXCL12-CXCR4 interaction used to be considered exclusive (unlike for other chemokines and their receptors), but recently it was suggested that CXCL12 is also bound by CXCR7 receptor.
The gene for CXCL12 is located on human chromosome 10. In human and mouse both CXCL12 and CXCR4 show high identity of sequence: 99% and 90%, respectively.

Background
DPP4 protein, also known as Dipeptidyl peptidase-4 or CD26, is a cell surface protease with diverse functions in cell signaling and metabolism. This research aims to investigate the role of DPP4 protein in various physiological processes and its implications in disease pathogenesis. Understanding the biological significance of DPP4 can provide insights into its potential as a therapeutic target for several disorders.
Function of DPP4 Protein:
DPP4 protein is involved in the cleavage and regulation of several peptide hormones and chemokines, influencing their bioactivity and half-life. It is widely expressed in various tissues, including immune cells, endothelial cells, and epithelial cells. DPP4 can modulate immune responses, glucose metabolism, and neuropeptide signaling through enzymatic and non-enzymatic activities.
Role of DPP4 Protein in Immune Regulation:
DPP4 protein plays a role in immune cell activation and regulation. It is expressed on the surface of T cells, where it functions as a co-stimulatory molecule. DPP4 engagement on T cells promotes T cell activation, cytokine production, and adhesion to endothelial cells. Additionally, DPP4 can cleave and inactivate certain chemokines, thereby influencing chemotaxis and immune cell recruitment.
Implications of DPP4 Protein in Metabolic Disorders:
DPP4 protein is involved in glucose metabolism and insulin regulation. It cleaves incretin hormones, such as glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP), which play crucial roles in glucose homeostasis. Inhibition of DPP4 activity can enhance the action of these incretin hormones, leading to improved glycemic control. Therefore, DPP4 inhibitors have been developed as antidiabetic drugs.
Association of DPP4 Protein with Cardiovascular Diseases:
DPP4 protein has been implicated in the pathogenesis of cardiovascular diseases. Elevated DPP4 levels have been observed in patients with heart failure, atherosclerosis, and hypertension. DPP4 can contribute to endothelial dysfunction, inflammation, and vascular remodeling, which are key factors in the development and progression of cardiovascular disorders. Inhibition of DPP4 activity has shown potential as a therapeutic strategy in preclinical studies.
Given its involvement in various biological processes and disease pathogenesis, DPP4 protein has emerged as a potential therapeutic target. DPP4 inhibitors, which prevent the enzymatic activity of DPP4, have been developed for the treatment of type 2 diabetes. These inhibitors enhance the action of incretin hormones, leading to improved glycemic control. Additionally, ongoing research aims to explore the therapeutic potential of DPP4 inhibitors in other conditions, such as immune-mediated disorders and cardiovascular diseases.
Conclusion:
The investigation of DPP4 protein provides insights into its diverse functions in cell signaling, immune regulation, and metabolism. Understanding the role of DPP4 in disease pathogenesis opens avenues for the development of targeted therapies for conditions such as diabetes, cardiovascular diseases, and immune-mediated disorders. Further research on DPP4 protein and its associated pathways may uncover new therapeutic opportunities and improve patient outcomes.

More Info

Introduction
Mouse Lungkine/CXCL15 (WECHE) belongs to the ELR motif-containing CXC chemokines. The mouse Lungkine gene has been mapped to chromosome 5. The cDNA of mouse Lungkine encodes a 166 amino acids (aa) protein with a 25 aa predicted signal peptide and a 141 aa mature protein with an exceptionally long C-terminal tail which extends beyond beyond the chemokine fold. Lungkine protein is secreted into bronchoalveolar space and is involved in lung-specific neutrophils trafficking. Furthermore, studies in Lungkine knockout mice propose that Lungkine is an imperative mediator of neutrophil migration from the lung parenchyma into the airspace. In addition, Lungkine is chemotactic for bone marrow progenitor cells and modulates hematopoietic cell differentiation. By Northern blot analysis and in-situ hybridization, Lungkine transcripts have only been specifically detected in the adult and fetal lung, and its expression is up-regulated under inflammatory conditions. There is a 35% aa sequence similarity between the mouse Lungkine and the human ENA-78 and a 31% similarity with the human IL-8.

Introduction
MDC (CCL22) is a small cytokine that belongs to the CC chemokine family. CCL22 is one of several Cys-Cys (CC) cytokine genes clustered on the q arm of chromosome 16. MDC shows chemotactic activity for natural killer cells, chronically activated T lymphocytes, monocytes and dendritic cells. On the other hand, MDC shows a mild activity for primary activated T lymphocytes and has no chemoattractant activity for neutrophils, eosinophils and resting T lymphocytes. MDC may also have a role in the trafficking of activated T lymphocytes to inflammatory sites and other aspects of activated T lymphocyte physiology. MDC interacts with cell surface chemokine receptors CCR4.
CCL22 is vastly expressed in macrophage and in monocyte-derived dendritic cells, and thymus. CCL22 is also found in the lymph node, appendix, activated monocytes, resting and activated macrophages. Lower expression of CCL22 can be seen in the lung and the spleen and very weak expression in the small intestine. In the lymph node CCL22 is expressed in a mature subset of Langerhans' cells (CD1a+ and CD83+).
Furthermore, CCL22 is expressed in atopic dermatitis, allergic contact dermatitis skin, and psoriasis, in both the epidermis and dermis. In addition, MDC has a role in hindering progression of lung cancer. Moreover, significantly higher CCL22 expression is linked to gastric cancer.

Introduction
CTLA-4 is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

Background
Title: Cytotoxic T-Lymphocyte Associated Antigen-4 Human Recombinant: A Potential Immunotherapeutic Target
Abstract:

Cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) is a key immune checkpoint receptor that plays a crucial role in regulating T-cell responses. This research paper provides an in-depth analysis of human recombinant CTLA-4, focusing on its production, characterization, and potential applications in immunotherapy. The paper discusses the significance of CTLA-4 in immune regulation, tumor immunity, and autoimmune diseases. Furthermore, it explores ongoing research and clinical trials investigating the therapeutic potential of recombinant CTLA-4 in various pathological conditions. The information presented in this paper aims to enhance our understanding of human recombinant CTLA-4 and its utility as a research tool and a potential immunotherapeutic agent.
Introduction:

Cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) is a cell surface receptor primarily expressed on T-cells. It functions as a negative regulator of T-cell activation, dampening immune responses to prevent excessive inflammation. Human recombinant CTLA-4, produced through genetic engineering techniques, provides researchers with a valuable tool to study its biological functions and explore its therapeutic potential.
Production and Characterization:

Recombinant CTLA-4 is typically generated using expression systems such as mammalian cells or bacteria. The protein is then purified and characterized to ensure its structural integrity and functional activity. Quality control measures are implemented to confirm the specificity and bioactivity of the recombinant CTLA-4.
Role in Immune Regulation:

CTLA-4 plays a critical role in immune regulation by downregulating T-cell activation and suppressing immune responses. It competes with the co-stimulatory receptor CD28 for binding to its ligands, CD80 and CD86, on antigen-presenting cells. This interaction inhibits T-cell activation and promotes immune tolerance. Recombinant CTLA-4 serves as a valuable tool for studying immune checkpoint mechanisms and their impact on immune responses.
Therapeutic Implications:

The blockade of CTLA-4 has emerged as a promising immunotherapeutic strategy in cancer treatment. Monoclonal antibodies targeting CTLA-4, such as ipilimumab, have shown significant clinical efficacy in enhancing anti-tumor immune responses. Recombinant CTLA-4-based therapies, including fusion proteins and engineered T-cell receptors, are being explored as potential immunotherapeutic interventions. Additionally, CTLA-4 plays a role in autoimmune diseases, making it a potential target for the development of novel treatments.
Conclusion:

Human recombinant CTLA-4 is a valuable research tool and a potential immunotherapeutic target. Its production, characterization, and applications in immune regulation contribute to our understanding of T-cell biology and the development of novel immunotherapies. Continued research and clinical trials investigating the therapeutic potential of recombinant CTLA-4 offer promising prospects for improving outcomes in cancer and autoimmune diseases.
