Development of small-molecule fluorescent probes targeting neutrophils via N-formyl peptide receptors

N-formyl peptide receptors (FPRs) are membrane receptors that are abundantly expressed in innate immune cells, including neutrophils and platelets, demonstrating potential new targets for immune system regulation and the treatment of inflammatory conditions. We report here the development and bio-physical validation of new FPR imaging agents as effective tools to track FPR distribution, localisation and… Continue reading Development of small-molecule fluorescent probes targeting neutrophils via N-formyl peptide receptors

Neutrophil adhesion to vessel walls impairs pulmonary circulation in COVID-19 pathology

Abstract Microthrombus formation is associated with COVID-19 severity; however, the detailed mechanism remains unclear. In this study, we investigated mouse models with severe pneumonia caused by SARS-CoV-2 infection by using our in vivo two-photon imaging system. In the lungs of SARS-CoV-2-infected mice, increased expression of adhesion molecules in intravascular neutrophils prolonged adhesion time to the… Continue reading Neutrophil adhesion to vessel walls impairs pulmonary circulation in COVID-19 pathology

FAP-targeted radioligand therapy with 68Ga/177Lu-DOTA-2P(FAPI)2 enhance immunogenicity and synergize with PD-L1 inhibitors for improved antitumor efficacy

Background Fibroblast activation protein (FAP)-targeted radioligand therapy, with immunomodulatory effects, has shown efficacy in both preclinical and clinical studies. We recently reported on a novel dimeric FAP-targeting radiopharmaceutical, 68Ga/177Lu-DOTA-2P(FAPI)2, which demonstrated increased tumor uptake and prolonged retention in various cancers. However, further exploration is required to understand the therapeutic efficacy and underlying mechanisms of combining… Continue reading FAP-targeted radioligand therapy with 68Ga/177Lu-DOTA-2P(FAPI)2 enhance immunogenicity and synergize with PD-L1 inhibitors for improved antitumor efficacy

Antibodies against the multifaceted cathepsin D protein open new avenues for TNBC immunotherapy

Triple-negative breast cancer (TNBC) is a heterogeneous breast cancer subtype characterized by aggressive clinical behavior and poor prognosis. The immune landscape associated with TNBC often reveals high immunogenicity. Therefore, immunotherapy, which has demonstrated its efficacy in different cancer types, could be a promising strategy for TNBC, given the limited therapeutic options currently available besides conventional… Continue reading Antibodies against the multifaceted cathepsin D protein open new avenues for TNBC immunotherapy
