چکیده

Background Our recent data have shown that a subset of CD8BTLA was the strongest predictive biomarker of response to adoptive T cell therapy using tumor-infiltrating lymphocytes. BTLA, B-and-T lymphocyte attenuator, is known as an inhibitory molecule in different immune cells. Its cytoplasmic region contains three motifs (Grb2, ITIM, and ITSM). ITIM and ITSM are inhibitory motifs that suppress T cell function upon ligation of the BTLA ligand, HVEM (Herpes virus entry mediator). However, the physiological function of Grb2 motif, known to interact with p85 PI3K, remains unclear. The aim of this study was to investigate the role of the Grb2 motif of BTLA in CD8 TIL and murine CD8 T cells.

Multifaceted Role of BTLA in the Control of CD8+ T-cell Fate after Antigen Encounter.

Purpose: Adoptive T-cell therapy using autologous tumor-infiltrating lymphocytes (TIL) has shown an overall clinical response rate 40%-50% in metastatic melanoma patients. BTLA (B-and-T lymphocyte associated) expression on transferred CD8+ TILs was associated with better clinical outcome. The suppressive function of the ITIM and ITSM motifs of BTLA is well described. Here, we sought to determin...

Uncovering a novel function of BTLA on tumor-infiltrating CD8+ T cells

Manipulation of T-cell co-inhibitory molecules, such as CTLA-4, PD-1, and BTLA has recently moved to the forefront of cancer immunotherapy. Although these molecules serve as inhibitors of T-cell activation, they are also biomarkers for activated T cells and may in fact have positive immune regulatory functions under certain circumstances. Recently, we demonstrated an unexpected positive associa...

CD8 T Cell Memory to a Viral Pathogen Requires Trans Cosignaling between HVEM and BTLA

Defining the molecular interactions required to program activated CD8 T cells to survive and become memory cells may allow us to understand how to augment anti-viral immunity. HVEM (herpes virus entry mediator) is a member of the tumor necrosis factor receptor (TNFR) family that interacts with ligands in the TNF family, LIGHT and Lymphotoxin-α, and in the Ig family, B and T lymphocyte attenuato...

BTLA marks a less-differentiated tumor-infiltrating lymphocyte subset in melanoma with enhanced survival properties

In a recent adoptive cell therapy (ACT) clinical trial using autologous tumor-infiltrating lymphocytes (TILs) in patients with metastatic melanoma, we found an association between CD8+ T cells expressing the inhibitory receptor B- and T-lymphocyte attenuator (BTLA) and clinical response. Here, we further characterized this CD8+BTLA+ TIL subset and their CD8+BTLA- counterparts. We found that the...

The inhibitory HVEM-BTLA pathway counter regulates lymphotoxin receptor signaling to achieve homeostasis of dendritic cells.

Proliferation of dendritic cells (DC) in the spleen is regulated by positive growth signals through the lymphotoxin (LT)-beta receptor; however, the countering inhibitory signals that achieve homeostatic control are unresolved. Mice deficient in LTalpha, LTbeta, LTbetaR, and the NFkappaB inducing kinase show a specific loss of CD8- DC subsets. In contrast, the CD8alpha- DC subsets were overpopu...
