Atezolizumab is an immune checkpoint inhibitor targeting PD-L1. The COSMIC-021 trial assessed the effectiveness of combining cabozantinib with atezolizumab in patients diagnosed with advanced RCC, including both clear cell and non-clear cell subtypes. The results showed that in patients with advanced cc...

Therefore, it is the most urgent task to further elucidate the mechanism of immune checkpoint inhibitor resistance, discover multitumor universal biomarkers, and develop new target agents to improve the response rate of immunotherapy in patients. In this study, the mechanism of anti㏄D/PD㎜1 drug...
Oncology Frontier-Hematology Frontier:This study provides important information that PD one inhibitor plus chemotherapy is highly effective for the average patient. So could you share your ideas of future research. I think the two main challenges are to identify biomarkers, predictive of response or r...

The current study aimed to determine PD-1/ PD-L1 expression in MCL specimens and its significance as an immune check point inhibitor. Methods: This retrospective study was conducted on the formalin-fixed paraffin-embedded blocks of 79 confirmed MCL patients based on immunohistochemistry (IHC)....

Fig.5D). After the co-culturing of CD4+T cells with NC-OE and FSTL3-OE CRC cells, the proportion of Tregs (CD25+Foxp3+T cells) among CD4+T cells increased in the FSTL3-OE group, while IDO1 inhibitor (1-MT) could weaken this change (Fig.5E). To investigate the mechanism of ...
The binding of PD-1 to its ligand programmed death-ligand 1 (PD-L1) activates downstream signaling pathways and inhibits T cell activation in the perspective of immune system mechanism and regulation in tumor progression. It is well reported that tumors adopt certain immune-checkpoint pathways as ...
However, CD28+ T-cell functional fitness was not improved by the absence of the 4 IRs evaluated, enforcing the role of PD1 alone in impairing the functional competence of CD8+ T cells through a CD28-dependent mechanism in peripheral blood of NSCLC patients. At variance, circulating PD1+CD28...
