Sex Differences in the Immune System Become Evident in the Perinatal Period in the Four Core Genotypes Mouse.

Front Endocrinol (Lausanne) 2021 27;12:582614. Epub 2021 May 27.

Division of Biomedical Sciences, School of Medicine, University of California, Riverside, Riverside, CA, United States.

We have used the four core genotypes (FCG) mouse model, which allows a distinction between effects of gonadal secretions and chromosomal complement, to determine when sex differences in the immune system first appear and what influences their development. Using splenic T cell number as a measure that could be applied to neonates with as yet immature immune responses, we found no differences among the four genotypes at postnatal day 1, but by day 7, clear sex differences were observed. These sex differences were unexpectedly independent of chromosomal complement and similar in degree to gonadectomized FCG adults: both neonatal and gonadectomized adult females (XX and XY) showed 2-fold the number of CD4+ and 7-fold the number of CD8+ T cells their male (XX and XY) counterparts.
