Cytotoxic T lymphocyte antigen-4 (CTLA-4) A49G polymorphism and autoimmune blood diseases [PDF]

open access: yesTurkish Journal of Hematology, 2010
OBJECTIVE: The cytotoxic T lymphocyte associated antigen-4 (CTLA-4) is expressed on T lymphocytes, and inhibits the T-cell responses. In animal models, it has been shown that complete CTLA-4 deficiency was lethal due to massive infiltration of tissues by

CTLA-4 and targeted immunotherapy—a key link in the systemic influence of periodontitis: a mini review [PDF]

open access: yesFrontiers in Dental Medicine
Cytotoxic T Lymphocyte Associated Protein 4 is a T cell-associated receptor that serves as an immune checkpoint molecule, downregulating immunosurveillance and propagating immune homeostasis.

Developing and characterizing a single-domain antibody (nanobody) against human cytotoxic T-lymphocyte-associated protein 4 (hCTLA-4) [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2021
Objective(s): Cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) is the most important human immune checkpoint that modulates T cells activity and brings about immune-homeostasis.

Toxicological and pharmacological assessment of AGEN1884, a novel human IgG1 anti-CTLA-4 antibody. [PDF]

open access: yesPLoS ONE, 2018
CTLA-4 and CD28 exemplify a co-inhibitory and co-stimulatory signaling axis that dynamically sculpts the interaction of antigen-specific T cells with antigen-presenting cells.

Elaborating on anti CTLA-4 mechanisms of action using an agent-based modeling approach

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Anti CTLA-4 therapy is aimed at blocking the Cytotoxic T-lymphocyte antigen-4 (CTLA-4), a key cancer immunity cycle checkpoint. The mechanism of action of CTLA-4 may be described as a dynamic competition for the B7 ligand which, subsequently, interferes ...

Identification of CTLA-4-Positive Cells in the Human Tonsil

open access: yesCells, 2021
CTLA-4 (cytotoxic T-lymphocyte-associated protein 4) was originally defined as a T-lymphocyte antigen and was used as a target in cancer immunotherapy. Unfortunately, the existence of CTLA-4 in cells other than T-lymphocytes is often overlooked. The goal

Immune-checkpoint blockade of CTLA-4 (CD152) in antigen-specific human T-cell responses differs profoundly between neonates, children, and adults

open access: yesOncoImmunology, 2021
The monoclonal antibody against CTLA-4, Ipilimumab, is a first-in-class immune-checkpoint inhibitor approved for treatment of advanced melanoma in adults but not extensively studied in children. In light of the fact that the immune response early in life

Characterization of the high-affinity anti-CTLA-4 monoclonal antibody JS007 for immune checkpoint therapy of cancer

open access: yesmAbs, 2023
Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is a critical inhibitory checkpoint molecule, and monoclonal antibodies (mAbs) targeting CTLA-4 that restore anti-tumor T cell immunity have achieved clinical success.

Molecules that inhibit T-cell functions: cytochemical localization and shuttling

open access: yesEuropean Journal of Histochemistry, 2009
Adaptive immune responses to antigens are mediated by specific receptors expressed on B cells (BCR’s) and T cells (TCR’s). Effector cells and memory cells are produced following a proliferative wave that accounts for clonal expansion.

CTLA-4 promotes lymphoma progression through tumor stem cell enrichment and immunosuppression

open access: yesOpen Life Sciences, 2021
The recurrence rate of lymphoma is very high, and tumor stem cells may be an important mechanism. Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) can inhibit antitumor immunity and promote cancer progression, but its role and mechanism in lymphoma ...
