Combination immunotherapy with anti-PD-L1 antibody and depletion of regulatory T cells during acute viral infections results in improved virus control but lethal immunopathology [PDF]

, 2020
Combination immunotherapy (CIT) is currently applied as a treatment for different cancers and is proposed as a cure strategy for chronic viral infections. Whether such therapies are efficient during an acute infection remains elusive.

Granzymes in cytolytic lymphocytes − to kill a killer?

Immunology & Cell Biology, 2004
Granzymes (gzm) are major components of the granules of cytolytic lymphocytes, natural killer and cytotoxic T cells. Their generally accepted mode of action consists of their directed secretion towards a virus‐infected or neoplastic target cell and perforin‐dependent delivery to the target cell cytosol, where they engage in various actions resulting in

Granzymes A and B serum levels in allo-SCT [PDF]

Bone Marrow Transplantation, 2008
Activated cytotoxic T lymphocytes and natural killer cells, which are involved in the pathogenesis of GVHD and viral infections after SCT produce granzymes (Grs). This study performed an ELISA in the serum of 86 patients at various time points before and after Allo-SCT to investigate GrA and GrB levels as potential markers for these serious ...

Single‐Cell Profiling Across Immune Tissues and Organs Reveals Immunosenescence Signatures in Male Rhesus Monkeys

Advanced Science, EarlyView.
Single‐cell profiling across bone marrow, spleen, mesenteric lymph, and blood in rhesus monkeys reveals organ Immunosenescence. GZMB rises with age, particularly in cytotoxic and terminally exhausted CD8+ T cells, and BHLHE40 emerges as a key transcription factor enriched across multiple CD8+ subsets, regulating pro‐inflammatory and exhaustion‐related ...

Alopecia areata: a multifactorial autoimmune condition [PDF]

, 2019
Alopecia areata is an autoimmune disease that results in non-scarring hair loss, and it is clinically characterised by small patches of baldness on the scalp and/or around the body. It can later progress to total loss of scalp hair (Alopecia totalis) and/

Cuproptosis and Disulfidptosis Converge to Empower PD‐L1 Checkpoint Therapy via Cadict‐Induced PD‐L1 Translation

Advanced Science, EarlyView.
This study introduces Cadict, an EGFR‐targeted nanodrug that co‐delivers cuproptosis and disulfidptosis inducers to overcome immune resistance. Cadict synergistically enhances tumor cytotoxicity and sensitizes cancers to ICIs by upregulating PD‐L1 via an Eif5b‐dependent translation mechanism, fostering a potent antitumor immune response and ...

G-Protein Coupled Receptor 18 Contributes to Establishment of the CD8 Effector T Cell Compartment. [PDF]

, 2018
The requirements for effector and memory CD8 T cell development are incompletely understood. Recent work has revealed a role for G-protein coupled receptor 18 (GPR18) in establishment of the intestinal CD8αα intraepithelial lymphocyte compartment.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

Advanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

CD8+ T cells in situ in different clinical forms of human cutaneous leishmaniasis

Revista da Sociedade Brasileira de Medicina Tropical, 2013
Introduction Leishmania braziliensis infection induces a large spectrum of lesions that clinically manifest as nodules or papules that progress to ulcers. Although it is already known that T helper cells predominate in the lesions, cytotoxic T cells have

pH/ROS‐Responsive Injectable Hydrogel Co‐Loaded with B7‐H3 Blocker and NETs Suppressor Boosts OSCC Synergistic Immunotherapy

Advanced Science, EarlyView.
A pH/ROS‐dual‐responsive injectable hydrogel, formed by dynamic boronic ester and Schiff base crosslinking, co‐delivers enoblituzumab (B7‐H3 blocker) and Cl‐amidine (NETs suppressor). Via localized intratumoral delivery, it synergistically reprograms the immunosuppressive tumor microenvironment, overcomes T cell infiltration barriers, restores ...
