[Glucose transporters in lymphocytes: expression and effects on lymphocyte functions].

Glucose uptake by lymphocytes is dependent on the facilitative glucose transporters (GLUT1, GLUT3, GLUT4, and GLUT6) of the GLUT family and the Na-coupled glucose transporter SGLT1. GLUTs and SGLTs are widely expressed in mammals, and their expression and functions may affect cell development, homeostasis, activation, and differentiation. This article details the important functions of several GLUTs and SGLTs in lymphocytes and points out that glucose transporters play a key role in supplying energy for lymphocytes, maintaining intracellular glucose homeostasis, and improving the efficiency of immune responses, which reflect their key roles in signal transduction. Probing into the effects of glucose transporters on lymphocyte functions will help to decipher the functioning mechanisms of lymphocytes in diseases. Furthermore, this paper prospects the application values of glucose transporters in lymphocytes from molecular biology, aiming to provide better strategies for the clinical treatment of lymphocyte-related diseases and promote the research and development of targeted therapeutic drugs.
