PMID- 15723806 OWN - NLM STAT- MEDLINE DCOM- 20050401 LR - 20210103 IS - 1074-7613 (Print) IS - 1074-7613 (Linking) VI - 22 IP - 2 DP - 2005 Feb TI - Homing phenotypes of tumor-specific CD8 T cells are predetermined at the tumor site by crosspresenting APCs. PG - 175-84 AB - Expression of tissue-specific homing molecules directs antigen-experienced T cells to particular peripheral tissues. In studies using soluble antigens that focused on skin and gut, antigen-presenting cells (APCs) within regional lymphoid tissues were proposed to be responsible for imprinting homing phenotypes. Whether this occurs in other sites and after physiologic antigen processing and presentation is unknown. We define in vivo imprinting of distinct homing phenotypes on monospecific T cells responding to antigens expressed by tumors in intracerebral, subcutaneous, and intraperitoneal sites with efficient brain-tropism of CD8 T cells crossprimed in the cervical lymph nodes (LNs). Multiple imprinting programs could occur simultaneously in the same LN when tumors were present in more than one site. Thus, the identity of the LN is not paramount in determining the homing phenotype; this critical functional parameter is dictated upstream at the site of antigen capture by crosspresenting APCs.
