evidence showed that chemokines serve as pro-migratory factors for immune cells. ccl3, ccl4 and ccl5, as the main cc  chemokines subfamily members, activate immune cells through binding to cc chemokine receptor 5 or ccr5. macrophages, nk cells and t lymphocytes express ccr5 and thus, affected ccr5 expression or functions could be associated with altered immune responses. deletion of 32 base pai...

Gene association studies are less appealing in cancer compared to autoimmune diseases. Complexity, heterogeneity, variation in histological types, age at onset, short survival, and acute versus chronic conditions are cancer related factors which are different from an organ specific autoimmune disease, such as Grave’s disease, on which a large body of multicentre data is accumulated. For years t...

Immune-complex-mediated injury is thought to play a role in diseases such as rheumatoid arthritis, systemic lupus erythematosus, serum sickness, various infectious diseases, and malignancies. With increased appreciation of the biological and pathological significance of circulating immune complexes has come efforts to develop appropriate techniques for identifying and measuring them. Common app...

Host genetic factors play a central role in determining the clinical phenotype of human diseases. Association between two polymorphic loci in human genome, human leukocyte antigen (HLA) and killer cell immunoglobulin-like receptors (KIRs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. Hence, defining the influence of genetic di...

Inflammation is a series of complex biological responses to protect the host from pathogen invasion. Chronic inflammation is considered a major cause of diseases, such as various types of inflammatory/autoimmune diseases and cancers. Spleen tyrosine kinase (Syk) was initially found to be highly expressed in hematopoietic cells and has been known to play crucial roles in adaptive immune response...

The role of various environmental factors in the pathogenesis of immune mediated diseases is well established. Of which, factors entailing an immune adjuvant activity such as infectious agents, silicone, aluminium salts and others were associated with defined and non-defined immune mediated diseases both in animal models and in humans. In recent years, four conditions: siliconosis, the Gulf war...

The immune system is one of our most complex biological systems in the body. Immunization may be active or passive. The active immunization involves stimulation with an antigen to develop immunological defences against a future exposure and passive immunization involves administration of preformed antibodies to an individual who is already exposed to be exposed to an antigen. Immunomodulatory a...
