This review explores advancements in cytokine engineering for regenerative medicine, highlighting the development of modified cytokines with enhanced stability and tissue-targeting, potentially improving treatments for chronic wounds and fibrotic diseases by promoting tissue healing and minimizing inflammation, while adapting concepts from cancer immunotherapy.

This article outlines treatment options and counseling recommendations for pediatric alopecia areata, highlighting shared decision-making based on disease severity and patient goals, with newer treatments like JAK inhibitors and dupilumab requiring attention to cost and side effects.

This study found that γδ T cells in the skin contribute to wound healing after vaccinia virus infection by promoting cytokine and growth factor induction, without affecting virus replication control.

This narrative review found that ritlecitinib shows consistent effectiveness and a favorable safety profile for treating alopecia areata in clinical trials and real-world settings, with progressive hair regrowth observed, particularly when treatment is initiated early and maintained appropriately.

This study links scalp pruritus in lichen planopilaris and its variants to the inflammation-induced release of substance P and calcitonin gene-related peptide by sensory nerves around hair follicle inflammation sites.

This review summarizes current treatments for recalcitrant alopecia areata and recent therapeutic developments targeting specific immunological pathways, reporting no new clinical results.

This review suggests that 308 nm excimer therapy may offer a well-tolerated non-pharmacologic option for alopecia areata, with more limited evidence for its effectiveness in lichen planopilaris and frontal fibrosing alopecia.

This review highlights that a comprehensive approach combining pharmacological, immunomodulatory, and regenerative interventions, including phototherapy enhanced with topical treatments and JAK inhibitors, appears effective and promising in the management of vitiligo by addressing its autoimmune and melanocyte-loss aspects.

In this study, researchers observed that dandruff involves altered keratinocyte activity and a low-grade inflammatory response characterized by increased interleukin-17-producing T-cells and CCL17 levels, but without significant changes in immune cell populations or skin barrier lipids.

In this study, researchers created a detailed human skin cell atlas by analyzing over 700,000 cells, finding that disrupted communication among specific immune and stromal cell subsets may play a key role in initiating and sustaining chronic skin inflammation in atopic dermatitis.

This review examines current understanding of how skin microbiota interact with and influence wound healing, highlighting the roles of commensal microorganisms in inflammation resolution, tissue regeneration, and barrier restoration, and discusses potential microbiota-based therapies for improving wound management.
