Glucocorticoids induce effector T cell depolarization via ERM proteins, thereby impeding migration and APC conjugation.

Impeding Migration and APC Conjugation Depolarization via ERM Proteins, Thereby Glucocorticoids Induce Effector T Cell

The roles of EPIYA sequence to perturb the cellular signaling pathways and cancer risk

Abstract It was shown that several pathogenic bacterial effector proteins contain the Glu-Pro-Ile-Tyr-Ala (EPIYA) or a similar sequence. These bacterial EPIYA effectors are delivered into host cell via type III or IV secretion system, where they undergo tyrosine phosphorylation at the EPIYA sequences, which triggers interaction with multiple host cell SH2 domain-containing proteins and thereby...

CD43 interaction with ezrin-radixin-moesin (ERM) proteins regulates T-cell trafficking and CD43 phosphorylation

Cell polarization is a key feature of cell motility, driving cell migration to tissues. CD43 is an abundantly expressed molecule on the T-cell surface that shows distinct localization to the migrating T-cell uropod and the distal pole complex (DPC) opposite the immunological synapse via association with the ezrin-radixin-moesin (ERM) family of actin regulatory proteins. CD43 regulates multiple ...

PKCθ Regulates T Cell Motility via Ezrin-Radixin-Moesin Localization to the Uropod

Cell motility is a fundamental process crucial for function in many cell types, including T cells. T cell motility is critical for T cell-mediated immune responses, including initiation, activation, and effector function. While many extracellular receptors and cytoskeletal regulators have been shown to control T cell migration, relatively few signaling mediators have been identified that can mo...

ERM proteins in cancer progression.

Members of the ezrin-radixin-moesin (ERM) family of proteins are involved in multiple aspects of cell migration by acting both as crosslinkers between the membrane, receptors and the actin cytoskeleton, and as regulators of signalling molecules that are implicated in cell adhesion, cell polarity and migration. Increasing evidence suggests that the regulation of cell signalling and the cytoskele...
