Phosphoantigen-reactive V gamma 9V delta 2 T cells represent the main innate human gamma delta T cell subset and dominate the fetal and adult peripheral blood gamma delta T cell repertoire. It has been hypothesized that adult blood V gamma 9V delta 2 T cells find their origin in the fetus like it is established for mouse innate gamma delta T cells....

To evaluate soluble Fas antigen (sFas), sFas ligand (sFasL), soluble tumor necrosis factor-related apoptosis-inducing ligand, and soluble cytoplasmic Bcl-2 protein (sBcl-2) serum levels, Fas and Bcl-2 expressions in T and B lymphocytes and monocytes and relations with erythrocyte sedimentation rate, C-reactive protein (CRP), Childhood Myositis Asse...

In the absence of a more effective vaccine against TB and in the interest of developing one, it is essential to understand immune responses associated with BCG protection. We comprehensively characterized T cell populations in BCG-vaccinated children over time. Blood from 78 healthy, BCG-vaccinated children representing four age groups (

Leukocytes are coated with glycans that modulate immune function through interactions with lectins. Here, the authors characterize the N-glycan repertoire of human tonsillar B cells. They report that Gal-9 is an intrinsic regulator of B cell activation that may differentially modulate BCR signaling at steady state and within germinal centers due to...
Background: Invasive lobular breast cancer (ILC) is the second most common histological subtype of breast cancer after invasive ductal cancer (IDC). Here, we aimed at evaluating the prevalence, levels, and composition of tumor-infiltrating lymphocytes (TILs) and their association with clinico-pathological and outcome variables in ILC, and to compar...
Breast tissue is very sensitive to ionizing radiation due to the presence of reproductive hormones, including estrogen. In the present pilot study, the efficiency of mammography X-rays to induce DNA double strand breaks (DSB) in mammary epithelial cells was investigated. For this, freshly resected healthy breast tissue was irradiated with 30 kV mam...
Background: Polycystic kidney disease (PKD) is characterized by urinary tract infections and extrarenal abnormalities such as an increased risk of cancer. As mutations in polycystin-1 and -2 are associated with decreased proliferation of immortalized lymphoblastoid cells in PKD, we investigated whether lymphopenia could be an unrecognized trait of ...

The success of cancer immunotherapy through the adoptive transfer of cytotoxic T lymphocytes (CTLs) is highly dependent on the potency of the elicited anti-tumor responses generated by the transferred cells, which can be hindered by a variety of upregulated immunosuppressive pathways. Downregulation of these pathways in the T cells via RNA interfer...

T cell receptor (TCR) signaling without CD28 can elicit primary effector T cells, but memory T cells generated during this process are anergic, failing to respond to secondary antigen exposure. We show that, upon T cell activation, CD28 transiently promotes expression of carnitine palmitoyltransferase 1a (Cpt1a), an enzyme that facilitates mitochon...

The assessment of tumor infiltrating lymphocytes (TILs) has recently emerged as a prognostic biomarker in several solid tumors. Quantification and subtyping of TILs reflects the immune response in the tumor microenvironment, contributing to either tumoral immune attack or escape and thereby affecting outcome. Despite the growing evidence of its val...
