We profiled the humoral response in the penis, an area that has been minimally explored

infections. Comparing paired tissue samples from 20 men at risk of HIV infection, foreskin
contains less immunoglobulin A (IgA) and more IgG2 than colon. Using foreskin dermal and
epidermal explants and paired plasma from 17 men, we examined Ig accumulation by
normalizing Ig to human serum albumin (HSA) transudation. Dermal IgM, IgG2, IgA, and IgE …
