1. Introduction T-cells are essential immune cell types and play a key role in adaptive immune responses, implicated in host defense against invading pathogens and antitumor immunity. The two main subtypes—CD4+ helper T (Th) cells and CD8+ cytotoxic T-cells—continuously recirculate between blood and the secondary lymphoid organs in the naïve quiescent form, requiring minimal metabolic activity.

The increasing burden of cutaneous wound infections with drug-resistant bacteria underlines the dire need for novel treatment approaches. Here, we report the preparation steps, characterization, and antibacterial efficacy of novel chitosan-coated Prussian blue nanoparticles loaded with the photosensitizer fluorescein isothiocyanate-dextran (CHPB-FD).

A team of researchers from Singapore has reported the development of a skin-mimicking scaffold by parallelly aligning nanofibers made up of a mixture of polycaprolactone (PCL) and gelatin that enhances wound healing. Their research has recently been published in Advanced Fiber Materials. When the skin is injured, it can take a while to heal, depending on the level of injury.
