Adult astrocytes display stronger immunosuppression than neonatal cells, regardless of sex differences. ConA-induced T cell proliferation in cultures without (black bars) astrocytes, with female and male neonatal astrocytes (grey bars) or female and male adult astrocytes (white bars). Each dot represents a distinct astrocyte preparation. Representative data of one out of 2 independent experiments are reported as proliferation index [c.p.m. + antigen/c.p.m. media] and represented as mean ± SEM
