This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This review highlights the role of chronic stress, oxidative stress, and immune processes in the development of Hashimoto’s thyroiditis and polycystic ovary syndrome, emphasizing the potential of antioxidants in their treatment based on the existing literature.

This study found that human γδTregs promoted hair regrowth and restored hair follicle immune privilege in a model of alopecia areata, suggesting potential for cell-based therapy in autoimmune diseases.

This research highlights advancements in understanding and treating psoriasis, finding that targeted therapies like IL-17 and IL-23 inhibitors show promise, but challenges such as adverse events, treatment resistance, and the need for personalized approaches remain.

Hemp seed biomaterials may reduce hair loss and improve hair growth.

In this animal study, the researchers found that biodegradable extracellular matrix scaffolds accelerated wound healing and enhanced hair follicle neogenesis in mice, suggesting a role for immune systems in tissue regeneration.

This study observed that, contrary to common belief, aged Balb/C mice showed better wound healing than younger mice despite greater weight loss, possibly due to increased T regulatory cells.

This study found that dysregulated microRNA expression in mice may be linked to aberrant gene activity that contributes to the development of alopecia areata.

This review discusses rodent models of alopecia areata and suggests they are crucial for understanding the autoimmune mechanisms and potential treatments but reports no new clinical results.
