Localization of gamma/delta T cells to the intestinal epithelium is independent of normal microbial colonization
نویسندگان
چکیده
Using monoclonal antibodies identifying all gamma/delta and alpha/beta T cell receptors in cytofluorometric analysis, we have compared the composition of intestinal intraepithelial lymphocytes (i-IEL) in euthymic and athymic germ-free (GF) and conventional (SPF) mice. The results show a marked influence of microbial colonization in the numbers of single-positive (CD4+ or CD8+) alpha/beta i-IEL, but little effect in the pool size or characteristics of gamma/delta i-IEL. In young athymic mice, virtually no alpha/beta i-IEL are detected, while considerable numbers of gamma/delta i-IEL remain, though reduced in GF animals.

Ontogenic development and tissue distribution of V gamma 1-expressing gamma/delta T lymphocytes in normal mice
A hamster monoclonal antibody (mAb) recognizing an epitope in the V gamma 1-J gamma 4-C gamma 4 chain of the gamma/delta T cell receptor has been generated. Using this mAb, we have quantitated the occurrence of V gamma 1-bearing gamma/delta T cells in the developing thymus and in the lymphoid organs and several epithelia of adult mice. The V gamma 1-expressing cells constitute a minor gamma/del...
متن کاملThymic origin of embryonic intestinal gamma/delta T cells
Current evidence suggests both thymic and extrathymic origins for T cells. Studies in mice favor an in situ origin for a prominent population of intestinal intraepithelial lymphocytes that express gamma/delta T cell receptor (TCR). This developmental issue is explored in an avian model in which the gamma/delta lymphocytes constitute a major T cell subpopulation that is accessible for study duri...
متن کاملThe T cell receptor in normal and inflamed human conjunctiva.
The majority of human peripheral blood and lymphoid tissue T cells express the TCR alpha/beta heterodimer, while the TCR gamma/delta is expressed on only a small subset of T lymphocytes. However, the majority of murine intraepithelial lymphocytes and most Thy-1+ murine dendritic epidermal cells express the TCR gamma/delta. Selective homing of avian TCR gamma/delta bearing lymphocytes to the int...
متن کاملGamma delta T cells of the murine vagina: T cell response in vivo in the absence of the expression of CD2 and CD28 molecules.
While little is known about their activation requirements and function, the intraepithelial T cells of the murine vagina express TCR complexes in which the antigen recognition components and the signaling components have unusual features. These vaginal T cells express an invariant V gamma 4/V delta 1 TCR and appear to be the only intraepithelial gamma delta T cells that exclusively use FcR gamm...
متن کاملEvidence for an association between Wnt-independent -catenin intracellular localization and ovarian apoptotic events in normal and PCO-induced rat ovary
The association of secreted frizzled related protein type 4 (Sfrp4) as an antagonist of Wnt mole-cules in apoptotic events has been reported previously. Moreover, its increased expression has been reported in the ovary of women with polycystic ovary (PCO). We have demonstrated in-creased Sfrp4 in PCO-induced rat ovary related to an increased number of apoptotic follicles showing nuclear ?cateni...
