LRBA deficiency impairs autophagy and contributes to enhanced antigen presentation and T-cell dysregulation

Abstract excerpt

Reduced autophagy is associated with the aberrant humoral response observed in lipopolysaccharide-responsive beige-like anchor protein (LRBA) deficiency; however, the molecular mechanisms and their impact on T-cell responses remain poorly understood. We identify two novel LRBA interactors, phosphoinositide 3-kinase regulatory subunit 4 (PIK3R4) and FYVE And Coiled-Coil Domain Autophagy Adaptor 1 (FYCO1), which...
