Design and synthesis of novel 8-(azaindolyl)-benzoazepinones as potent and selective ROCK inhibitors

AI SummaryThis article discusses the design and synthesis of novel 8-(azaindolyl)-benzoazepinones as potent and selective ROCK inhibitors. Through a core-hopping strategy and virtual screening workflow, potent inhibitors were identified by replacing the central core with a benzoazepinone ring. Compound 15 showed sub-nanomolar potencies in biochemical and cellular assays, along with remarkable selectivity over PKA. HDX… Continue reading Design and synthesis of novel 8-(azaindolyl)-benzoazepinones as potent and selective ROCK inhibitors

Circumventing resistance within the Ewing sarcoma microenvironment by combinatorial innate immunotherapy

AI SummaryThis article discusses the use of combinatorial innate immunotherapy to overcome resistance within the Ewing sarcoma microenvironment. The study shows that a chimeric antigen receptor (CAR) NK cell targeting MCAM, combined with NKTR-255 (IL-15 agonist) and Magrolimab (CD47 blockade), significantly enhances NK cell cytotoxicity and macrophage phagocytic activity against ES cells. Results from in… Continue reading Circumventing resistance within the Ewing sarcoma microenvironment by combinatorial innate immunotherapy

S100A9 and HMGB1 orchestrate MDSC-mediated immunosuppression in melanoma through TLR4 signaling

AI SummaryThis study investigates the role of S100A9 and HMGB1, acting through TLR4 signaling, in the immunosuppression mediated by myeloid-derived suppressor cells (MDSC) in melanoma. The researchers found that exposure to S100A9 and HMGB1 converted monocytes into MDSC through TLR4 signaling. Additionally, elevated plasma levels of S100A8/9 correlated with shorter progression-free survival in melanoma patients.… Continue reading S100A9 and HMGB1 orchestrate MDSC-mediated immunosuppression in melanoma through TLR4 signaling

Intratumoral CXCL13+ CD160+ CD8+ T cells promote the formation of tertiary lymphoid structures to enhance the efficacy of immunotherapy in advanced gastric cancer

AI SummaryThis study explores the role of intratumoral CXCL13+ CD160+ CD8+ T cells in promoting the formation of tertiary lymphoid structures (TLSs) to enhance the efficacy of immunotherapy in advanced gastric cancer. The researchers found that responders to immunochemotherapy had higher levels of TLSs and CXCL13+ CD160+ CD8+ T cells, which led to better outcomes.… Continue reading Intratumoral CXCL13+ CD160+ CD8+ T cells promote the formation of tertiary lymphoid structures to enhance the efficacy of immunotherapy in advanced gastric cancer

The Lysine Acetyltransferase PCAF Functionally Interacts with Estrogen Receptor Alpha in the Hippocampus of Gonadally Intact Male–But Not Female–Rats to Enhance Short-Term Memory

AI SummaryThe study explores the interaction between the lysine acetyltransferase PCAF and estrogen receptor alpha (ERĪ±) in the hippocampus of male rats in enhancing short-term memory (STM). The research indicates that PCAF, known for its role in long-term memory (LTM) through epigenetic processes, also influences STM possibly through nongenomic ER activity. The interaction was specific… Continue reading The Lysine Acetyltransferase PCAF Functionally Interacts with Estrogen Receptor Alpha in the Hippocampus of Gonadally Intact Male–But Not Female–Rats to Enhance Short-Term Memory

Targeting IL-33 reprograms the tumor microenvironment and potentiates antitumor response to anti-PD-L1 immunotherapy

AI SummaryThis study focused on the use of IL-33 targeting to enhance the antitumor response to anti-PD-L1 immunotherapy by reprogramming the tumor microenvironment. The research demonstrated that blocking IL-33 using a fusion protein in combination with anti-PD-L1 treatment increased T cell responses, inhibited tumor progression, and provided long-term protective immunity. Targeting both IL-33 and PD-L1… Continue reading Targeting IL-33 reprograms the tumor microenvironment and potentiates antitumor response to anti-PD-L1 immunotherapy

Adenovirus vaccine targeting kinases induces potent antitumor immunity in solid tumors

AI SummaryThis article discusses the development and effectiveness of an adenovirus vaccine targeting kinases AURKA and CDK7 in inducing potent antitumor immunity in solid tumors. The vaccine was successful in preventing tumor growth, increasing immune cell infiltration, promoting dendritic cell subsets, and inducing long-lasting antitumor effects by generating memory CD8+ T cells. The study suggests… Continue reading Adenovirus vaccine targeting kinases induces potent antitumor immunity in solid tumors
