Combined therapeutic strategy based on blocking the deleterious effects of AGEs for accelerating diabetic wound healing.

Diabetic foot ulcer is a serious complication of diabetes. Excessive accumulation of advanced glycation end products (AGEs) is one of the critical pathogenic factors in postponing diabetic wound healing. The main pathogenic mechanisms of AGEs include inducing cellular dysfunction, prolonging inflammatory response, increasing oxidative stress and reducing endogenous nitric oxide (NO) production.

Quaternized antimicrobial peptide mimics based on harmane as potent anti-MRSA agents by multi-target mechanism covering cell wall, cell membrane and intracellular targets.

Infectious disease caused by methicillin-resistant Staphylococcus aureus (MRSA) seriously threatens public health. The design of antimicrobial peptide mimics (AMPMs) based on natural products (NPs) is a new strategy to kill MRSA and slow the development of drug resistance recently. Here, we reported the design and synthesis of novel AMPMs based on harmane skeleton.

Screening of cell-virus, cell-cell, gene-gene crosstalk among animal kingdom at single cell resolution.

Background: The exact animal origin of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains obscure and understanding its host range is vital for preventing interspecies transmission.

Methods: Herein, we applied single-cell sequencing to multiple tissues of 20 species (30 data sets) and integrated them with public resources (45 data sets covering 26 species) to expand the virus receptor distribution investigation. While the binding affinity between virus and receptor is essential for viral infectivity, understanding the receptor distribution could predict the permissive organs and tissues when infection occurs.

Endothelial cell heterogeneity and microglia regulons revealed by a pig cell landscape at single-cell level.

Pigs are valuable large animal models for biomedical and genetic research, but insights into the tissue- and cell-type-specific transcriptome and heterogeneity remain limited. By leveraging single-cell RNA sequencing, we generate a multiple-organ single-cell transcriptomic map containing over 200,000 pig cells from 20 tissues/organs. We comprehensively characterize the heterogeneity of cells in tissues and identify 234 cell clusters, representing 58 major cell types.

VThunter: a database for single-cell screening of virus target cells in the animal kingdom.

Viral infectious diseases are a devastating and continuing threat to human and animal health. Receptor binding is the key step for viral entry into host cells. Therefore, recognizing viral receptors is fundamental for understanding the potential tissue tropism or host range of these pathogens.
