T cell exclusion causes resistance to cancer immunotherapies via immune checkpoint blockade (ICB). Myeloid cells contribute by expressing signal regulatory protein-α (SIRPα), an inhibitory membrane receptor that interacts with ubiquitous CD47 control macrophage phagocytosis in the tumor microenvironment. Although CD47/SIRPα-targeting drugs have been assessed preclinical models, therapeutic benefit of selectively blocking SIRPα, and not SIRPγ/CD47, humans remains unknown. We report a potent...
Abstract Regulatory T cells (Treg) impede effective antitumor immunity. However, the role of Tregs in clinical outcomes patients with triple-negative breast cancer (TNBC) remains controversial. Here, we found that an immunosuppressive TNBC microenvironment is marked by imbalance between effector αβCD8+ and harboring hallmarks highly suppressive (eTreg). Intratumoral eTregs strongly expressed PD-1 persisted resistant to blockade. Importantly, CD25 was most selective surface marker primary...
Dendritic cells (DC) can achieve cross-presentation of naturally-occurring tumor-associated antigens after phagocytosis and processing dying tumor cells. They have been used in different clinical settings to vaccinate cancer patients. We previously gamma-irradiated MART-1 expressing melanoma as a source patients by injecting irradiated with BCG GM-CSF or load immature DC use them vaccine. Other trials IFN-gamma activated macrophage killer (MAK) treat However, the MAK has based on their...
OSE-127 is a humanized mAb targeting the IL-7Rα-chain (CD127), under development for inflammatory and autoimmune disease treatment. It strict antagonist of IL-7R pathway, not internalized by target cells, noncytotoxic. In this work, first-in-human, phase I, randomized, double-blind, placebo-controlled, single-center study was carried out to determine safety, pharmacokinetics, pharmacodynamics, immunogenicity administration. Sixty-three healthy subjects were randomly assigned nine groups: six...
Membrane Fcgamma receptors (FcgammaRs) can act either as potent activators of effector cell functions or inhibitors receptor-mediated activation following engagement by IgG antibodies bound to their target molecules. The remarkable ability activating FcgammaRs trigger antibody-dependent cellular cytotoxicity, cytokine release and phagocytosis/endocytosis followed antigen presentation has stimulated the development a number therapeutic monoclonal whose Fc regions have been engineered optimize...
<h3>Background</h3> Regulatory T cells (Tregs) inhibit immune responses in solid cancers using cell-cell contacts and anti-inflammatory cytokine release. Also, due to high constitutive levels of IL2Ralpha chain (CD25) expression, Tumor infiltrating (TIL)-Tregs preferably consume local Interleukin-2 (IL2), thus depriving conventional from IL2-induced activation proliferation. Therefore, the selective depletion TIL-Tregs therapeutic antibodies targeting CD25 represents a promising strategy...
Abstract Background: Some receptors are active in the absence of ligand and actively trigger cell death through apoptosis. These called “dependence receptors” (DRs) as their expression at surface renders cells critically dependent for survival on availability. Deleted Colorectal Carcinoma (DCC) UNC5H prototypic DRs which induce apoptosis unless netrin-1 is present. It has been shown that up-regulated a large fraction tumors interference with netrin-1/receptors interaction associated...
