    More Info

    • Introduction

      HCV is a small 50nm, enveloped, single-stranded, positive sense RNAvirus in the family Flaviviridae. HCV has a high rate of replication with approximately one trillion particles produced each day in an infected individual. Due to lack of proofreading by the HCV RNA polymerase, the HCV has an exceptionally high mutation rate, a factor that may help it elude the host's immune response. Hepatitis C virus is classified into six genotypes(1-6) with several subtypes within each genotype. The preponderance and distribution of HCV genotypes varies globally. Genotype is clinically important in determining potential response to interferon-based therapy and the required duration of such therapy. Genotypes 1 and 4 are less responsive to interferon-based treatment than are the other genotypes (2, 3, 5 and 6).

    • Introduction

      IL-18 is a proinflammatory cytokine. This cytokine can induce the IFN-gamma production of T cells. The combination of this cytokine and IL12 has been shown to inhibit IL4 dependent IgE and IgG1 production, and enhance IgG2a production of B cells. IL-18 binding protein (IL18BP) can specifically interact with this cytokine, and thus negatively regulate its biological activity.

    • Background

      Also known as IFN-gamma inducing factor, Interleukin-18 or IL18 is a protein. In humans this protein is encoded by the IL18 gene. The protein is a proinflammatory cytokine.

      Mechanism
      The levels of IL-18 in the human body are increased at sites of inflammation. This includes cases of rheumatoid arthritis as well as other similar conditions. Osteoblastic cells express the protein and it is capable of inhibiting osteoclast formation. It is able to do this through a variety of mechanisms.
      For instance, it is able to stimulate GM-CSF. This is created by T cells and is a response to treatment using IL-18. As well as this, the cytokine does stimulate INF-y production through vivo in bone. Furthermore, the impact on bone resorption and osteoclastogenesis is increased when used in conjunction with IL-12 treatment. Studies have shown that IL-18 provides an indirect stimulus on osteoclastogenesis due to the effect it has on T lymphocytes.
      Furthermore, evidence has shown that IL-18 does increase the production of OPG. This was studied in research on transgenic mice that overexpressed IL-18. In these cases osteoclasts decreased as did bone mass. This suggested that IL-18 also has an impact on bone growth.

      Interactions
      Research has also explored the different interactions of IL-18 on other proteins. This includes the interaction between IL-18 and IL-18R. This has been shown to decrease the power of protective immunity and increase pathogenic responses during an infection involving intracellular bacteria. This interaction suggests that the presence or absence of IL-18R signal does impact the pathogenic compared to protective immunity.
      Another interaction between interleukin 19 and Astrocyte has shown that it can improve neuropathic pain processing following nerve injury. It is proposed this is due to the fact that the nociceptive signals in the spinal cord are augmented due to this reaction.

      Function
      Belonging to the IL-1 superfamily, this cytokine is produced by macrophages as well as various other cells. It operates after binding with the interleukin-18 receptor. Working with IL-12, the protein is then able to induce-cell mediated immunity after an infection from lipopolysaccharide and other microbial products.
      Once stimulated by IL-18 other cells including natural killer and T cells then release IFN-y. This type II IFN plays a crucial part in activating the macrophages of various other cells.
      Together IL12 and IL-18 are able to successfully inhibit IgE and IG1 production that is dependent on IL-4. As well as this, the protein is also able to increase IgG2a production through B cells. IL-18 will interact specifically with this type of cytokine and has a negative impact on regulation of biological activity.

      Structure
      Many researchers have suggested that the structure of IL-18 is a key way to understand it’s receptor activation mechanism. The structure of IL-18 closely resembles of IL-1 and has various similarities. It is folded into a beta-trefoil structure and three sites have been shown to be important for receptor activation. These were revealed through extensive mutagenesis. Two of the sites provide binding sites for the IL-18 receptor and are located in positions similar to IL-1. The third structure seems to be used for IL-18 receptor beta binding.

    • Introduction

      CCL20 is a chemotactic factor that draws lymphocytes & neutrophils, rather than monocytes. MIP-3 alpha inhibits proliferation of myeloid progenitors in colony formation assays. MIP3A plays a role in the formation and function of the mucosal lymphoid tissues by attracting lymphocytes and dendritic cells towards epithelial cells. C-terminal processed forms have been shown to be equally chemotactically active for leukocytes. CCL20 holdes antibacterial activity e.coli atcc 25922 and s.aureus atcc 29213. CCL20 gene transcription is activated by H. pylori, which activates NF-kappaB through intracellular signal pathway which involves IkappaB kinase and NF-kappaB-inducing kinase. MIP-3 alpha is invloved in chemokine-mediated lymphocyte trafficking during gastric inflammation in Helicobacter infection. CCL20 expression is involved in the recruitment of CD45R0-positive T cell subsets into the intestinal lamina propria.
      MIP-3A is in charge of the advancement of pulpal inflammation through the recruitment of C-C motif Receptor 6-expressing lymphocytes Vaginal epithelial cells respond to factors present in semen by secreting MIP-3 alpha, which increases langerhans cells recruitment during HIV transmission.

    • Introduction

      HCV is a small 50nm, enveloped, single-stranded, positive sense RNAvirus in the family Flaviviridae. HCV has a high rate of replication with approximately one trillion particles produced each day in an infected individual. Due to lack of proofreading by the HCV RNA polymerase, the HCV has an exceptionally high mutation rate, a factor that may help it elude the host's immune response. Hepatitis C virus is classified into six genotypes(1-6) with several subtypes within each genotype. The preponderance and distribution of HCV genotypes varies globally. Genotype is clinically important in determining potential response to interferon-based therapy and the required duration of such therapy. Genotypes 1 and 4 are less responsive to interferon-based treatment than are the other genotypes (2, 3, 5 and 6). HCV NS3 Genotype-3a contains 2 domains which are serine protinase and helicase.

    • Introduction

      H3N2 is a subtype of the influenza A virus. Its name derives from the forms of the two kinds of proteins on the surface of its coat, hemagglutinin (H) and neuraminidase (N). H3N2 exchanges genes for internal proteins with other influenza subtypes. H3N2 has tended to dominate in prevalence over H1N1, H1N2, and influenza B. H3N2 strain descended from H2N2 by antigenic shift, in which genes from multiple subtypes re-assorted to form a new virus. Both the H2N2 and H3N2 strains contained genes from avian influenza viruses.
      H3N2 viruses are able to infect mammals and birds. In pigs, humans, and birds, the virus has mutated into many strains. Hemagglutinin(HA) binds to sialic acid-containing receptors on the cell surface, generating the attachment of the virus particle to the cell. HA has a vital part in the determination of host range restriction and virulence and is in charge of the diffusion of the virus into the cell cytoplasm by facilitating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane.

    • Introduction

      A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.

      The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.

      While bats are possibly the host of 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

    • Introduction

      Borrelia belongs to a genus of bacteria of the spirochete phylum. Borrelia causes borreliosis, which is a zoonotic, vector-borne disease transmitted mainly by ticks and some by lice, depending on the species. Of the 36 known species of Borrelia, 12 are distinguished to cause Lyme disease or borreliosis and are transmitted by ticks. The main Borrelia species causing Lyme disease are Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. The Borrelia genus members have a linear chromosome which is about 900 kbp in length as well as an excess of both linear and circular plasmids in the 5-220 kbp size range. The plasmids are atypical, as compared to most bacterial plasmids, since they contain many paralogous sequences, a large number of pseudogenes and, in some cases, essential genes. Moreover, a number of the plasmids have features suggesting that they are prophages.
