Introduction: Sex differences associated with inflammation have been observed across numerous autoimmune and cardiometabolic conditions. We aim ed to explore the differential impact of sex hormones/sex chromosomes on molecular pathways potentially relevant for immune cell functions using a unique post-pubertal transgender cohort.Methods: RNA-sequencing was performed on peripheral blood mononuclear cells (PBMCs) from a he...

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...
