shown to increase Foxp3+ regulatory T-cell frequencies among CD4+ T cells in mice. We
now investigated whether pharmacological targeting of the acid sphingomyelinase, which
catalyzes the cleavage of sphingomyelin to ceramide and phosphorylcholine, also allows to
manipulate relative CD4+ Foxp3+ regulatory T-cell frequencies in humans. Pharmacological
acid sphingomyelinase inhibition with antidepressants like sertraline, but not those without …
