Porcine γδ T Lymphocytes Can Be Categorized into Two Functionally and Developmentally Distinct Subsets according to Expression of CD2 and Level of TCR

Porcine γδ T lymphocytes can be categorized into two functionally and developmentally distinct subsets according to expression of CD2 and level of TCR.

Porcine γδ T cells have two levels of TCRγδ expression. Whereas TCRγδ(med) cells are mostly CD2(+)CD8(-) and CD2(+)CD8(+), TCRγδ(hi) cells are highly enriched for CD2(-)CD8(-). This distribution is independent of bacterial colonization and it is already established in the thymus prior to export of γδ cells to the periphery. Sorting and cultivation experiments revealed that CD2(-)CD8(-) γδ cells...

Porcine gd T Lymphocytes Can Be Categorized into Two Functionally and Developmentally Distinct Subsets according to Expression of CD2 and Level of TCR

Two physically, functionally, and developmentally distinct peritoneal macrophage subsets.

The peritoneal cavity (PerC) is a unique compartment within which a variety of immune cells reside, and from which macrophages (MØ) are commonly drawn for functional studies. Here we define two MØ subsets that coexist in PerC in adult mice. One, provisionally called the large peritoneal MØ (LPM), contains approximately 90% of the PerC MØ in unstimulated animals but disappears rapidly from PerC ...

γδ-TCR+ CD2– lymphocytes are recruited into bovine mammary gland after stimulation

γδ-T-Cell Receptor (TCR) lymphocytes were detected in mammary gland lavages collected from 10 clinically healthy virgin heifers before and after intramammary stimulation with synthetic muramyl dipeptide analogue. Using two-colour flow cytometry, CD2+ and CD2– subsets of γδ-TCR lymphocytes were analyzed. CD2+ γδ-TCR lymphocytes markedly prevailed over CD2– cells in intact mammary gland: 88.9 ± 4...
