The TGFβ receptor inhibitor galunisertib showed promising efficacy in patients with pancreatic ductal adenocarcinoma (PDAC) in the phase 2 H9H-MC-JBAJ study. TGFβ inhibition redirects macrophage polarization to M1, reducing Lif and shifting PDAC cells to a more epithelial/classical phenotype, improving gemcitabine sensitivity. This study supports exploring TGFβ-targeting agents in PDAC with a mesenchymal/basal-like ecotype driven by high CCL3 levels.
Epoetin alfa was used simultaneously in 31 patients (60.7%). The effect was particularly high in the IPSS-M low and very low groups. We believe that the relatively high response rate in our patients was influenced by the frequent use of a higher dose (1.75 mg/kg) and especially by adding ESA to luspatercept in poorly responding patients.
These findings suggest that Oxy210 could be a drug candidate for targeting both NASH and atherosclerosis, as well as chronic inflammation associated with the manifestations of metabolic syndrome.
Hmox1highiCAFs overexpressed the Cxcl10 receptor (Sdc4) and facilitated functional CD8+ T-cell infiltration through the Tnfsf9-Tnfrsf9 axis. Overall, our nanodrugs reshape the phenotype of CAFs and enhance functional CD8+ T-cell infiltration into tumors, holding the potential to be a safe and promising therapy for PDAC.
Despite some promising results, many therapies remain in early development or have faced setbacks, emphasizing the need for a more comprehensive understanding of the disease's pathobiology. Continued research into targeted therapies, homogenous clinical trial designs, as well as increased incorporation of molecular prognostic tools and artificial intelligence into trial design are essential for developing effective treatments for MDS and improving patient outcomes.
This year, luspatercept, an anti-anemic agent targeting the TGFβ pathway, became available for clinical use in Japan. Various research initiatives are currently underway to develop new medicines targeting specific molecules within innate immune and inflammasome-signaling pathways, including IL-1β, CD33, TLR, IRAK4, and p38MAPK.
The potential of the transforming growth factor-β (TGF-β) inhibitor (galunisertib) for treating NPC was also investigated using the proposed platform...This study highlights the significant impact of confinement levels, surface proteins, nanotopography, and the TGF-β inhibitor on the metastatic probability of cancer cells, providing valuable insights for the development of novel treatment therapies for NPC. The developed platforms proved to be useful tools for evaluating the metastatic potential of cells and are applicable for drug screening.
We hereby examined the effects of TGFβ depletion by AVID200/BMS-986416(TGFβ-TRAP), a TGFβ ligand trap, on the tumor microenvironment of pancreatic ductal adenocarcinoma (PDAC) murine models with different organ-specific metastasis...Notably, the most highly expressed ligands of CCR5 shifted from the immunosuppressive CCL5 to CCL7 and CCL8, which may mediate the immune agonist activity of CCR5 following TGFβ-TRAP and anti-PD-1 combination treatment. This study suggested that TGFβ depletion modulates CAF heterogeneity and potentially reprograms CAFs and myeloid cells into anti-tumor immune agonists in PDAC, supporting the validation of such effects in human specimen.
In silicosis female C57BL/6 mice model, oral CBD or pirfenidone (PFD) on day 1 after intratracheal drip silica (150 mg/mL) and continued for 42 days...In vitro experiments showed that CBD can effectively reduce the expression of NLRP3 inflammasome in THP-1 cells and subsequently block silica-stimulated transformation of fibromuscular-myofibroblast transition (FMT) by culturing human embryonic lung fibroblasts (MRC-5) in conditioned medium of THP-1 cells. Therefore, CBD exhibited the potential therapy for silicosis through inhibiting the silica-induced pulmonary inflammation and fibrosis via the NLRP3/TGF-β1/Smad2/3 signaling pathway.
CarboCell can be injected through standard thin-needle technologies and has inherent imaging contrast which secure accurate intratumoral positioning. In particular, here we report the therapeutic performance for a dual-drug CarboCell providing sustained release of a Toll-like receptor 7/8 agonist and a transforming growth factor-β inhibitor in preclinical tumor models in female mice.
In addition, antifibrotic effects, anti-caspase-3, and PCNA enhancement activity were recorded. PFD exhibited a protective potential and mitigated the MTX-induced testiculopathy via suppression of testicular oxidative stress, inflammation, fibrosis, and apoptosis and retaining the testicular proliferative efficacy as confirmed by histological, immunohistochemical, and biochemical methods.
