In this study, we contrasted the vascular endothelial cells (ECs) in EP lesions against those in psoriasis vulgaris and healthy controls. Utilizing single-cell RNA sequencing, immunofluorescence, and flow cytometry on human and mouse samples, we observed a marked increase and activation of EP ECs, which upregulated genes relative to angiogenesis, leukocyte adhesion and antigen presentation.

Doublecortin-like kinase 1 promotes stem cell-like properties through the Hippo-YAP pathway in prostate cancer.

m6A demethylation of NNMT in CAFs promotes gastric cancer progression by enhancing macrophage M2 polarization.

Cancer associated fibroblasts (CAFs) are the predominant stromal cells in the tumor microenvironment of gastric cancer (GC), interacting with both immune and tumor cells to drive cancer progression. However, the precise link between these interactions and their potential as therapeutic targets remains poorly understood. In this study, we identified for the first time that nicotinamide N-methyltransferase (NNMT) derived from CAFs promoted M2 macrophage polarization, which, in turn, facilitated the proliferation and migration of GC cells.

Expanding Cas12a Activity Control with an RNA G-Quadruplex at the 5' end of CRISPR RNA.

Precise control of Cas12a activity is essential for the improvement of the detection limit of clinical diagnostics and the minimization of errors. This study addresses the challenge of controlling Cas12a activity, especially in the context of nucleic acid detection where the inherent incompatibility between isothermal amplification and CRISPR reactions complicates accurate diagnostics. An RNA G-quadruplex (RG4) structure at the 5' end of crRNA is introduced to modulate Cas12a activity accurately without the need for chemical modifications.

However, the mechanisms of pathogenesis and host responses underlying serotype-specific disease outcomes remain poorly understood.

Effects of Yersinia pseudotuberculosis outer membrane vesicles on Pseudomonas aeruginosa antigens immune response.

Outer membrane vesicles (OMVs) are immunogenic self-adjuvanting vesicles produced by Gram-negative bacteria such as Pseudomonas aeruginosa and Yersinia pseudotuberculosis.
