Viruses and self- immune diseases (such as systemic lupus erythematosus ( SLE immune response)) exhibits gender differences
.
Both sex hormones and genes on the X chromosome are related to this gender difference
Viruses and self- immune diseases (such as systemic lupus erythematosus ( an immune SLE immune response)) exhibits gender differences
The study proved that DKO ABCs show gender differences in the following aspects: the number of ABCs characterized by CD11c and T-bet (as shown in the figure above), the up-regulation of interferon-stimulating genes ( ISG ) and effector B cells (germinal center ( GC) ) Differentiation of B cells and plasmablasts ( PB ) / plasma cells ( PC )) .
DKO females show more pronounced GC and PB/PC expansion than DKO males .

DKO females show more pronounced GC and PB/PC expansion than DKO males .
DKO ABCs subjected to clonal expansion and differentiate into oligonucleotides CD11c + and CD11c- effector B cell population, by B -cell receptor ( the BCR ) have proved sequencing and fate profiles two kinds of B cell populations and pathogenic pro-inflammatory functions .
Although from male and femaleDKO 's ABCs show similar BCR profiles, and their significant differences in function and differentiation indicate that they may adopt different molecular procedures
in conclusion:
Conclusion: Conclusion:Age-related B cells ( ABCs ) have gender differences in function and differentiation, and play an important regulatory role in antiviral responses and autoimmune diseases
