Abstract

T Lymphocyte Plasticity in Autoimmunity and Cancer.

Highlights

  • In this special issue, authors addressed topics related to the altered frequencies and functions of T lymphocyte subsets and the molecular and cellular mechanisms responsible for T cell lineage commitment, polarization, and reprogrammed adaptive responses in health and pathology

  • Among numerous immune suppressive mechanisms employed by cancer, BioMed Research International the deprivation of adenosine triphosphate (ATP) plays an important role as ATP is essential for T cell activation

  • Extracellular ATP concentration is maintained by the ectonucleotidase CD39 which is involved in the suppression of T lymphocyte activation by CD11c+ dendritic cells infiltrating tumors in the mouse lung LLC and mammary 4T1 cancer models, as described by M

Summary

Introduction

Authors addressed topics related to the altered frequencies and functions of T lymphocyte subsets and the molecular and cellular mechanisms responsible for T cell lineage commitment, polarization, and reprogrammed adaptive responses in health and pathology. T lymphocytes are essential for the development and regulation of adaptive immune responses. Upon engagement of their specific antigen receptor in presence of appropriate costimulatory signals and specific cytokines, naıve CD4+ and CD8+ T cells differentiate into specific effector or suppressor subsets exhibiting distinct phenotypic characteristics and functions.
