Toll-like Receptor 4 Deficiency Aggravates Airway Hyperresponsiveness and Inflammation by Impairing Neutrophil Apoptosis in a Toluene Diisocyanate-Induced Murine Asthma Model.

22 views | May 15 2020

Chen S et al. indicated that TLR4 deficiency promoted neutrophil infiltration by impairing its apoptosis via up-regulation of Bcl-2, thereby resulting in deteriorated AHR and airway inflammation, which suggests that TLR4 could be a negative regulator of TDI-induced neutrophilic inflammation.

Combination of PARP inhibitor olaparib, and PD-L1 inhibitor durvalumab, in recurrent ovarian cancer: a proof-of-concept phase 2 study.

34 views | May 15 2020

Lampert EJ et al. found that he PARPi and anti-PD-L1 combination showed modest clinical activity in recurrent ovarian cancer. Their correlative study results suggested immunomodulatory effects by olaparib/durvalumab in patients and indicate that VEGF/VEGFR pathway blockade would be necessary for improved efficacy of the combination [Read the Full Post]

anlotinib alters tumor immune microenvironment by downregulating PD-L1 expression on vascular endothelial cells

36 views | May 10 2020

Liu S et al. demonstrated that PD-L1 high expression on VECs inhibits the infiltration of CD8+ T cells, whereas promotes the aggregation of FoxP3+ T cells into tumor tissues, thus becoming an "immunosuppressive barrier". Anlotinib can ameliorate the immuno-microenvironment by downregulating PD-L1 expression on VECs to inhibit tumor growth. [Read the Full Post]
