common variable immunodeficiency (cvid) and selective iga deficiency (sigad) are the most common primary antibody deficiencies. these two diseases may have coincidence in one family and sigad can progress to cvid which suggest common underlying genetic defects between sigad and cvid. this study was designed to find the prevalence of multiple cases in families of iranian patients with cvid or si...

Gamma interferon (IFN-gamma) has been shown to inhibit replication of subgenomic and genomic hepatitis C virus (HCV) RNAs in vitro and to noncytolytically suppress hepatitis B virus (HBV) replication in vivo. IFN-gamma is also known for its immunomodulatory effects and as a marker of a successful cellular immune response to HCV. Therapeutic expression of IFN-gamma in the liver may therefore fac...

BACKGROUND In the glomerular mesangium, immunologic and/or infectious activation of the inflammatory, NF-kappaB-mediated signal pathway can induce a progression of already existing mesangial lesions in non-immunologic and immunologic glomerular disease. This progression is preceded by upregulated mesangial gene expression of which the vascular cell adhesion molecule-1, VCAM-1 (vascular cell adh...

Certain combinations of differentiation antigens are expressed on leukemia blasts and are absent or extremely rare among normal progenitors in the fetal liver and fetal and regenerating bone marrow. These combinations include cCD3/TdT, a thymic feature retained on thymic-acute lymphoblastic leukemia (T-ALL) blasts outside the thymus, and the coexpression of TdT and myeloid markers (CD13, CD33) ...
