Two papers in this issue of Neuron examine new aspects of Semaphorin signaling via Plexin receptors. Winberg et al. present evidence that the transmembrane protein Off-track (OTK) interacts biochemically and genetically with Plexin A and is important for Sema 1a repulsive signaling. Hu et al. examine the coupling of Plexin B to Rac and RhoA and propose that Plexin B signaling involves inhibitio...

Background Semaphorin (SEMA), initially identified as a neural guidance molecule, has been recently highlighted for its role in regulating the immune response. Among seven categories of SEMA, Class 4A SEMA (SEMA4A) involves T cell-mediated responses through expression itself dendritic cells. Objectives This study aimed to investigate SEMA4A systemic lupus erythematosus (SLE) and association bet...
