Machine learning-driven data analysis revealed a pattern of KLRG1 expression that uniquely identified intratumoral effector CD4 T cell populations that constitutively associate with tumor burden across tumor models, and are lost in tumors undergoing regression in response to ICB. Similarly, a Helios-...
BackgroundKLRG1 is a marker of terminally differentiated CD8+ T cells in viral infection, but its role in human Mycobacterium tuberculosis infection remains elusive.MethodsA set of cohorts of patients with tuberculosis was designed, and the expression profiles and functions of KLRG1+CD4+ T cells ...

KLRG1 has also been detected in a few bacterial infections, such asMycobacterium tuberculosis(Mtb) andHelicobacter pylori(H. pylori) [90,98]. During Mtb infection, KLRG1 is overexpressed on lung CD4+T-cells, and these KLRG1+CD4+T-cells secrete significantly greater amounts of IFN-γ, IL-2,...
2.1.2 Regulation of CD4 + T Cell Differentiation by TGFβ TGFβ can directly regulate the homeostasis and differentiation of the different types of CD4 + T cell subset, as detailed below. 2.1.2.1 Th1 Cells TGFβ is a strong suppressor of Th1 effector cell differentiation. Initial evidence cam...

(NK) cells, as well as distinct subsets of T-cells, such as CD8+T-cells, CD4+T-cells, and regulatory T-cells (Tregs) [2,3,4,5]. The extracellular domain of KLRG1 on immune cells can be assessed via immunofluorescence staining and flow cytometry using KLRG1-specific antibodies, enabling...
(3). KLRG1 is expressed as a 30 ‑ 40 kDa N‑glycosylated molecule that forms disulfide‑linked homodimers, trimers, and tetramers (4, 5). It is expressed on subpopulations of CD8+, CD4+, regulatory, and gamma/delta T cells as well as on NK cells (2, 4, 6 ‑ 8). KLRG1...
