Tumor‐Derived LAMB3 Drives Immunosuppressive LRRC15+ Fibroblast Formation During Pancreatic Ductal Adenocarcinoma Development

Advanced Science, EarlyView.
A single‐cell atlas of pancreatic ductal adenocarcinoma development reveals progressive ductal‐fibroblast‐immune crosstalk. Tumor‐derived LAMB3 drives the formation of immunosuppressive LRRC15+ fibroblasts through the ITGB1/FAK/MAPK/FOSL2 signaling. Glycolytic reprogramming upregulates LAMB3 and correlates with LRRC15+ fibroblast enrichment.

Stage-dependent expression of CD7, CD45RO, CD45RA and CD25 on CD4-positive peripheral blood T-lymphocytes in cutaneous T-cell lymphoma.

Acta Dermato-Venereologica, 1996
Flow cytometric analysis of T-cell surface markers in peripheral blood has revealed abnormal patterns in patients with cutaneous T-cell lymphomas (CTCL). Here we investigated CD7, CD25, CD45RO and CD45RA expression on CD4+ T-lymphocytes in patients with CTCL stage I/II and III/IV and in patients with severe inflammatory skin diseases (ISD), as well as ...

Canine tissue-associated CD4+CD8α+ double-positive T cells are an activated T cell subpopulation with heterogeneous functional potential.

PLoS ONE, 2019
Canine CD4+CD8α+ double-positive (dp) T cells of peripheral blood are a unique effector memory T cell subpopulation characterized by an increased expression of activation markers in comparison with conventional CD4+ or CD8α+ single-positive (sp) T cells.

Monitoring CD27 expression to evaluate Mycobacterium tuberculosis activity in HIV-1 infected individuals in vivo. [PDF]

, 2011
The level of bacterial activity is only poorly defined during asymptomatic Mycobacterium tuberculosis (MTB) infection. The objective was to study the capacity of a new biomarker, the expression of the T cell maturation marker CD27 on MTB-specific CD4 T ...

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Correlation of memory T cell responses against TRAP with protection from clinical malaria, and CD4+ CD25high T cells with susceptibility in Kenyans

, 2008
Background - Immunity to malaria develops naturally in endemic regions, but the protective immune mechanisms are poorly understood. Many vaccination strategies aim to induce T cells against diverse pre-erythrocytic antigens, but correlates of protection ...

Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

Advanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Human Immunodeficiency Virus Type 1 (HIV-1) Infection of Herpesvirus Saimiri-Immortalized Human CD4-Positive T Lymphoblastoid Cells: Evidence of Enhanced HIV-1 Replication and Cytopathic Effects Caused by Endogenous Interferon-γ

, 1997
Herpesvirus saimiri (HVS) is a nonhuman primate gamma herpesvirus which can immortalize human T lymphocytes similar to Epstein–Barr virus immortalization of B cells.
