Using a high-throughput screening (HTS) approach, a new GTP-site binding pyridine-carboxylate series of cGAS inhibitors was discovered. The biochemical potency of this new pyridine carboxylate series was improved 166-fold from the original hit to double-digit nanomolar levels using structure-based design insights, but the series was found to suffer from low permeability and low bioavailability. A structure-based hybridization of the metal-binding motifs of the pyridine carboxylate series and our previously disclosed tetrahydrocarboline GTP-site ligand identified pyrimidine amide compound .

- T follicular helper (Tfh) cells, which are important for antibody production, rely heavily on the immunoreceptor PD-1, and its deficiency leads to weakened Tfh functions and impaired immune responses in mice.
- Individuals lacking PD-1 or PD-L1 demonstrate fewer memory B cells and diminished antibody responses, highlighting the critical role of these molecules in immune system functionality.
- PD-1 influences both the intrinsic and extrinsic aspects of B cell memory and antibody production, suggesting that disruptions in PD-1 signaling can lead to complications in immune responses, especially during anti-PD-1-PD-L1 therapies.
Article Synopsis
- * Notably, early in the pandemic, Africa reported lower mortality rates from COVID-19, suggesting that certain demographic and socioeconomic factors may play a role in this disparity.
- * The review also discusses genetic influences, such as the protective role of type I interferon, and explores how elements like the microbiome and helminth parasites could modulate immune responses to respiratory viral infections.
Functionally characterizing the genetic alterations that drive pancreatic cancer is a prerequisite for precision medicine. Here, we perform somatic CRISPR/Cas9 mutagenesis screens to assess the transforming potential of 125 recurrently mutated pancreatic cancer genes, which revealed USP15 and SCAF1 as pancreatic tumor suppressors. Mechanistically, we find that USP15 functions in a haploinsufficient manner and that loss of USP15 or SCAF1 leads to reduced inflammatory TNFα, TGF-β and IL6 responses and increased sensitivity to PARP inhibition and Gemcitabine.

Background: Functional dystonia (FD) is a common subtype of functional movement disorder. FD can be readily diagnosed based on positive signs and is potentially treatable with rehabilitation. Despite this, clinical outcomes remain variable and a gold standard approach to treatment is lacking.
