PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Decrease in CD4 and CD8 lymphocytes are predictors of severe clinical picture and unfavorable outcome of the disease in patients with COVID-19

Open Medicine
The main objective of this study was to investigate the association between CD4+ and CD8+ lymphocyte values and disease severity, need for oxygen therapy and disease outcomes.

CDK4/6 Inhibition Induces CD8+ T Cell Antitumor Immunity via MIF‐Induced Functional Orchestration of Tumor‐Associated Macrophages

Advanced Science, EarlyView.
CDK4/6 inhibition promotes CD8+ T cell expansion through tumor‐macrophage crosstalk by activating HIF‐1α and enhancing MIF‐CD44/CD74 signaling. This reprograms TAMs to boost MHC‐I antigen presentation, and CDK4/6 inhibitor‐trained M1 TAM supernatant therapy synergizes with low‐dose PD‐1 blockade to restore antitumor immunity.

Reduced CD40L expression on ex vivo activated CD4+T-lymphocytes from patients with excellent renal allograft function measured with a rapid whole blood flow cytometry procedure [PDF]

, 2004
Background: The CD40-CD40L (CD154) costimulatory pathway plays a critical role in the pathogenesis of kidney allograft rejection. In renal transplant biopsies, CD4+ CD40L+ graft-infiltrating cells were detected during chronic rejection in contrast to ...

rWTC‐MBTA Vaccine, Alone and Enhanced with Anti‐PD1, Elicits Immune Responses against CNS and Peripheral B‐Cell Lymphoma

Advanced Science, EarlyView.
An autologous whole‐tumor‐cell vaccine (rWTC‐MBTA) is evaluated in murine CNS lymphoma. Subcutaneous vaccination activates dendritic cells, broadens T‐cell priming, and drives lymphocyte trafficking to brain tumors, producing durable tumor control. Longitudinal bioluminescence and adoptive‐transfer assays verify CNS engagement. Combination with anti‐PD‐

Immunoregulatory functions for murine intraepithelial lymphocytes: gamma/delta T cell receptor-positive (TCR+) T cells abrogate oral tolerance, while alpha/beta TCR+ T cells provide B cell help. [PDF]

, 1992
Past work has shown that a subset of effector T cells with unique characteristics could abrogate hapten- or antigen-induced tolerance, and the reconstitution of this immune response has been termed contrasuppression.

Differential effects of α4β7 and GPR15 on homing of effector and regulatory T cells from patients with UC to the inflamed gut in vivo [PDF]

, 2015
Objective: Gut homing of lymphocytes via adhesion molecules has recently emerged as new target for therapy in inflammatory bowel diseases. We aimed to analyze the in vivo homing of effector (Teff) and regulatory (Treg) T cells to the inflamed gut via ...

Induction of Secreted Human Immunodeficiency Virus Type 1 (HIV-1) Resistance Factors in CD4-Positive T Lymphocytes by Attenuated HIV-1 Infection

Virology, 2002
This report describes induction of HIV-1 resistance and synthesis of resistance factors in immortal CD4-positive T lymphocytes. SupT1 cells were infected by NL4-3 attenuated by a defect in the vif gene through coculture with infected primary lymphocytes. Cell lines from this infection, termed R1, expressed CD4 and CXCR4, carried low levels of HIV-1 DNA,

Targeting the PGRN‐BMP Lysosomal Axis With NPs@PGRN Reverses Immunometabolic Dysfunction in Chronic Septic Arthritis

Advanced Science, EarlyView.
Chronic septic arthritis involves intracellular bacterial persistence and lipid‐immune crosstalk via the PGRN‐BMP lysosomal axis. A dual‐targeting nanoparticle system (NPs@PGRN) restores lysosomal bactericidal function, reduces bacterial burden, and reprograms macrophage immunity, offering a novel therapeutic strategy. ABSTRACT Chronic septic arthritis,

Regulatory T-lymphocyte subsets in patients with HIV-infection receiving highly active antiretroviral therapy

Бюллетень сибирской медицины, 2019
Background. The reason why HIV-infected patients receiving highly active antiretroviral therapy (HAART) suffer from the increased immune activation remains elusive.
