Protamines are considered the most important structure in the sperm nucleus, and they are proteins with a significantly large amount of amino acids carrying a positive charge, which allows the formation of the tight package of the genomic DNA in the spermatozoa. Many authors studied the abnormalities in the protamine 1 (PRM1) and/or protamine 2 (PRM2) genes and reported their possible association...
Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease in which interleukin-4 (IL-4) plays an important role. This study aimed to investigate the influence of IL-4 variable number of tandem repeats (VNTRs) and IL-4-590 promoter polymorphisms on RA susceptibility, activity and severity in Egyptian population.One hundred and seventy-two RA patients and 172 controls were enrolled in this...
CD4 is a candidate gene in autoimmune diseases, including rheumatoid arthritis (RA). Because the CD4 receptor is crucial for appropriate antigen responses of CD4+ T cells, changes in CD4 expression and CD4+ T-cell activity may influence tolerance or tissue destruction in autoimmune diseases and contribute to their risk. We analyzed two polymorphisms of the CD4 in 172 female Egyptian patients with...
