Rapid acquisition of tissue-specific homing phenotypes by CD4(+) T cells activated in cutaneous or mucosal lymphoid tissues

Daniel J Campbell et al. J Exp Med. 2002.

Abstract

Effector and memory T cells can be subdivided based on their ability to traffic through peripheral tissues such as inflamed skin and intestinal lamina propria, a property controlled by expression of 'tissue-specific' adhesion and chemoattractant receptors. However, little is known about the development of these selectively homing T cell subsets, and it is unclear whether activation in cutaneous versus intestinal lymphoid organs directly results in effector/memory T cells that differentially express adhesion and chemoattractant receptors targeting them to the corresponding nonlymphoid site. We define two murine CD4(+) effector/memory T cell subsets that preferentially localize in cutaneous or intestinal lymphoid organs by their reciprocal expression of the adhesion molecules P-selectin ligand (P-lig) and alpha 4 beta 7, respectively. We show that within 2 d of systemic immunization CD4(+) T cells activated in cutaneous lymph nodes upregulate P-lig, and downregulate alpha 4 beta 7, while those responding to antigen in intestinal lymph nodes selectively express high levels of alpha 4 beta 7 and acquire responsiveness to the intestinal chemokine thymus-expressed chemokine (TECK). Thus, during an immune response, local microenvironments within cutaneous and intestinal secondary lymphoid organs differentially direct T cell expression of these adhesion and chemoattractant receptors, targeting the resulting effector T cells to the inflamed skin or intestinal lamina propria.

(Left) CD4 and CD45RB expression by lymphocytes isolated from the cutaneous PLNs of a >1-y-old BALB/c mouse.
