Since single and dual ICTs were not curative, T cell-activating ICTs were combined with a CXCR1/2 inhibitor targeting immunosuppressive myeloid cells. Triple therapy resulted in durable complete responses. Given similar profiles in human PDAC and the availability of these agents for clinical testing,...
嵌合抗原受体(car)是car-t的核心部件,赋予t细胞hla非依赖的方式识别肿瘤抗原的能力,这使得经过car改造的t细胞相较于天然t细胞表面受体tcr能够识别更广泛的目标。car的基础设计中包括一个肿瘤相关抗原(tumor-associatedantigen,taa)结合区(通常来源于单克隆抗体抗原结合区域的scfv段),一个胞外铰链区,一个跨膜区和一个...
Eight patients (7 cohort A; 1 cohort B) were treated with a total of 42 infusions on dose level 1 (1x107/3x107 CAR+ T cells/dose). Post-infusion, multiple participants exhibited neurologic findings suggestive of on-tumor CAR-T activation, including seizure, dysphasia, and localized pain....
Cells of solid tumors are sensitive to killing by activated T cells but can escape this killing activity by producing inhibitory molecules known as ‘checkpoint proteins’, such as the Programmed Death Ligand 1 (PD-L1), on their surface. When this occurs, activated T cells which...
Ligation of 4-1BB induces an activating signal in CD8+T cells and natural killer cells, resulting in increased pro-inflammatory cytokine secretion, cytolytic function, and antibody-dependent cell-mediated cytotoxicity. Targeting 4-1BB with agonistic monoclonal antibody (mAb) therapy demonstrated potent...

Description: This 4B4 (4B4-1) monoclonal antibody reacts with human CD137 (also known as 4-1BB or TNFRSF9), which is an inducible member of the TNFR family of costimulatory molecules expressed on T cells, natural killer cells, dendritic cells, granulocytes, and mast cells. Involved in ...
Furthermore, clinical outcomes suggest that the co-stimulatory domains in CARs support different T cell functions in patients. For example, while overall outcomes are similar between 41BB (19BBz) and CD28-containing CARs (1928z), 19BBz CAR T cells can persist for years in patients, but ...
Apoptotic cells were found in all cases examined, and their frequency increased significantly during acute rejection (0.17 vs. 9.0; P<0.05), The immunoreactivity of Fas and Fast antigen was higher in specimens with acute rejection than in those with stable graft function. Increase...
Activated T cells also express CD137, and engagement with CD137L enhances T cell proliferation, IL-2 secretion, survival, and cytotoxic activity. CD137L is also expressed on a majority of B-cell lymphomas, including mantle cell lymphoma, follicular lymphoma, and diffuse large...
