selective iga deficiency (igad) (serum iga concentration of pcr was used to type hla b, dr, and dq alleles in 29 iranian individuals with igad and 299 swedish individuals with igad. the results indicate a strong association with the hla b14, dr1 alleles in iranian subjects and hla b8, b12, b13, b14, b40, dr1, dr3, dr7, dq2 and dq5 alleles in swedish subjects. differences in hla association of i...

Abstract It has become increasingly evident that even though B cells respond to both soluble and membrane-presented antigens in vitro, the primary mode of antigen recognition vivo appears be on surfaces antigen-presenting cells. To determine how sense an is membrane associated, we investigated role Piezo1 mechanosensing cation channel human B-cell activation. We discovered flux calcium when sim...

Cryptococcosis, caused by Cryptococcus neoformans, has been demonstrated to be controlled by T helper (Th)1 cells while Th2 cells are associated with fungal growth and dissemination. Although cryptococcal immunoreactive protein antigens were previously identified, their association with Th1 or Th2 immune responses was not provided. In mice, Th1-dependent IFN-γ induces the production of IgG2a, w...
