Introduction
Exedin-4 Recombinant is a like peptide-1 receptor agonist. The native hormone is produced in the gut of Gila monster Heloderma suspectrum (a type of reptile found in the desert) that stimulates production without causing threateningly low blood sugar, which can occur after using some anti-diabetes products. Recently, researchers used extracted saliva from gila monsters to create an unprecedented breakthrough in Diabetes Type 2 treatment. Unlike other products taken for type 2 diabetes, Exedin-4 has not been linked with weight gain and actually resulted in weight loss, according to the researchers. Exedin-4 enhances glucose-dependant secretion, suppresses inappropriately elevated secretion and slows gastric emptying in vivo. It also promotes B-cell proliferation and neogenesis in vitro and in animal models. Exedin-4 stimulates an increase in acinar cAMP, without stimulating the release of amylase.

Introduction
Exenatide Derived from the saliva of the gila monster, is a 39 amino acid peptide that mimics the GLP-1 incretin, an insulin secretagogue with glucoregulatory effects. Typical responses to exenatide include improvements in the initial rapid release of endogenous insulin, suppression of glucagon release by the pancreas, regulation of gastric empyting, and reduced appetite - all of which function to lower blood glucose. Exenatide is self-regulating in that it lowers blood sugar when levels are elevated but does not continue to lower blood sugar when levels return to normal, unlike with sulfonylureas or insulins.

Background
Semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA), has emerged as a breakthrough in the field of diabetes management and metabolic disorders. It is recognized for its potent glucose-lowering effects, weight management properties, and cardiovascular benefits. Beyond diabetes, semaglutide is under investigation for its potential applications in obesity treatment and other related conditions. This research aims to comprehensively explore semaglutide, shedding light on its multifaceted mechanisms of action and its broader therapeutic implications.
The primary objective of this research is to elucidate the mechanisms underlying the glucose-lowering and metabolic effects of semaglutide. In vitro and in vivo experiments will be conducted to investigate how semaglutide interacts with GLP-1 receptors, influences insulin secretion, and modulates glucose homeostasis. Understanding these mechanisms is crucial for harnessing the full therapeutic potential of semaglutide.
The second objective is to assess the clinical relevance of semaglutide in diabetes management. Clinical trials involving individuals with type 2 diabetes will be conducted to evaluate the efficacy, safety, and long-term outcomes of semaglutide treatment. These investigations may provide valuable insights into its use as a monotherapy or adjunct therapy in diabetes care.
The third objective is to explore the potential applications of semaglutide beyond diabetes. Research will investigate its role in obesity treatment, cardiovascular risk reduction, and non-alcoholic fatty liver disease (NAFLD) management. Understanding the multifaceted properties of semaglutide may open new avenues for therapeutic interventions in various metabolic and cardiovascular conditions.
By delving into the diverse functions of semaglutide, this research aims to expand our understanding of its therapeutic potential and clinical applications. The findings may contribute to improved treatment strategies for individuals affected by diabetes, obesity, and related metabolic disorders.

Introduction
Wheat Gliadin and related gluten components from barley, rye and possibly oats can cause an abnormal immune response called Celiac disease which is a chronic gastrointestinal disorder. Celiac disease characteristics are flattening of the jejunal mucosa and intestinal lesions of variable severity in hereditarily inclined individuals. Even though Celiac disease is not a classic autoimmune disease it is related to anti-tissue transglutaminase antibodies and gliadin antibodies tests are most recommended in screening populations at risk for CD and other gluten-sensitive enteropathies. In the past, serologic tests for gliadin antibodies usually were not very precise and were not enough for accurate diagnosis due to missing deamidated epitopes within the authentic gliadin fraction traditionally used in diagnostic test kits. ProSpec's deamidated Gliadin isoform matches to the deamidated neo-epitopes, which in the natural antigen are formed by transglutaminase-mediated glutamine side chain deamidation.

Introduction
Liraglutide is a long-acting GLP1 analogue sharing 97% a.a. homology to human GLP1. Liraglutide differs from GLP1 by the substitution of arginine for lysine at position 34. While GLP1 is degraded swiftly by DPP4 resulting in short life of insulin, Liraglutide contains a fatty acid that binds to albumin and prolongs the half-life of the structure. liraglutide causes insulin to secret in the presence of increasing glucose levels. Due toits receptor site, liraglutide inhibits glucagon secretion and delays gastric emptying.

Introduction
Glucagon-like peptide-1 (GLP-1) is derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-1 as a guthormone. The biologically active forms of GLP-1 are: GLP-1-(7-37) and GLP-1-(7-36)NH2.
GLP-1 secretion by L cells is dependent on the presence of nutrients in the lumen of the small intestine. The secretagogues (agents that causes or stimulates secretion) of this hormone include major nutrients like carbohydrate, proteinand lipid. Once in the circulation, GLP-1 has a half life of less than 2 minutes, due to rapid degradation by the enzyme dipeptidyl peptidase-4.
GLP-1 possesses several physiological properties that make it a subject of intensive investigation as a potential treatment of diabetes mellitus. The known physiological functions of GLP-1 include: Increases insulin secretion from the pancreas in a glucose-dependent manner, decreases glucagon secretion from the pancreas, increases beta cells mass and insulin gene expression, inhibits acid secretion and gastric emptying in the stomach, decreases food intake by increasing satiety. -

Introduction
Elcatonin is a Calcitonin derivative which is transformed from eel´s calcitonin by changing the S-S bond into the stable C-N bond. It inhibits the absorption and autolysis of bones, thus leads to blood calcium descending. In addition, it inhibits the bone salts dissolving and transferring and promotes the excretion of calcium and phosphorus in urine. Meanwhile, it inhibits renal tubules reabsorbing calcium, phosphorus and sodium and keeps blood calcium at normal level. It is mainly used for remitting or eliminating the pain caused by Osteoporosis.

Introduction
EXOSC10 is a nucleolar protein and represents one crucial component of the so-called "PM/Scl complex" or "nuclear exosome", which is an RNA-processing complex consisting of a number of exoribonucleases (not to be confused with certain multivesicular bodies which are shed by cultured cells into the culture fluid and are also called exosomes).
Autoantibodies against EXOSC10 occur in patients suffering from polymyositis, scleroderma or polymyositis/scleroderma overlap syndromes. While antibodies to other components of the exosome complex (PM/Scl 75, several Rrp proteins) can be found in some sera, practically all patients with autoantibodies against the PM/Scl complex are positive for EXOSC10 antibodies, making this specificity an important marker. The presence of EXOSC10 autoantibodies is a comparatively "good" prognostic sign in polymyositis/scleroderma overlap syndrome unlike the poor prognosis seen when other myositis and systemic sclerosis specific autoantibodies are present. -

Background
Leptin is a hormone which mainly produced by adipocytes . Leptin’s main part is to regulate long-term energy balance. Leptin is encoded by the LEP gene. Leptin effects mainly on leptin receptors in the cell mambrane of various cells in the human body. The leptin receptor is found on a wide range of cell types. The leptin receptor is a single-transmembrane-domain type 1 cytokine receptor. leptin levels influence satiety, appetite and triggers behaviors which lead to energy savings High leptin levels are interpreted by the brain that energy reserves are high, whereas low leptin levels means that energy reserves are low, in the process adapting the organism to starvation through a variety of metabolic, neurobiochemical, endocrine and behavioral change.

Introduction
Terlipressin is similar to a naturally occurring hormone present in the body, known as antidiuretic hormone (ADH) or vasopressin. ADH has two main effects in the body. Firstly, it causes narrowing of blood vessels (vasoconstriction), thereby limiting blood flow to a particular area of the body. It also acts on receptors in the kidney to retain water in the body, which helps to prevent excessive loss of water in the urine. Terlipressin is commonly used to stop bleeding of varices in the food pipe (oesophagus). Varices are fragile distended veins that can occur in various parts of the body such as the oesophagus. This is caused by an increase in blood pressure in certain diseases such as severe liver disease. These fragile varices can rupture and lead to life threatening bleeding. Terlipressin is therefore given to narrow blood vessels, and so restricting blood flow to the varices and stopping the bleeding.

Introduction
VAMP8 also called endobrevin, is the main component of a SNARE complex involved in the docking and fusion of synaptic vesicles with the presynaptic membrane. VAMP8 protein is involved in the regulatation of enzyme secretion in pancreatic acinar cells and plays a part in the abscission of the midbody during cell division, which leads to completely separate daughter cells. VAMP8 is essential for dense-granule secretion in platelets. VAMP8 is related with the perinuclear vesicular structures of the early endocytic compartment. VAMP8 interacts particularly with the soluble NSF-attachment protein (alpha-SNAP), through an VAMP8-containing SNARE complex.
