People with hair loss have higher risk of high blood sugar and diabetes, and lower levels of a specific hormone.

This study found that CXCL12+ fibroblast subsets in mouse skin play a critical role in recruiting neutrophils and defending against S. aureus infection, with similar fibroblast activity observed in human psoriatic skin.

MicroRNA-21 could help diagnose and treat skin fibrosis.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

In this study, DHT was associated with increased production of proinflammatory cytokines IL-6 and TNF-α in cultured sebocytes, suggesting a role in acne pathophysiology beyond sebum production.

This study found that combining minoxidil and retinol additively promoted hair growth in vitro, enhancing Erk- and Akt-dependent pathways and preventing apoptosis in dermal papilla cells and keratinocytes.

This letter to the editor discusses a potential link between new onset alopecia areata and SARS-CoV-2 infection, but reports no new clinical results.

This study suggests that adipose-derived mesenchymal stem cells from diabetic mice can enhance wound healing by promoting fibroblast growth, migration, angiogenesis, and differentiation into fibroblasts and endothelial cells.

This study found that the selective PPARγ modulator GMG-43AC may inhibit unwanted hair growth by inducing catagen phase while preserving hair follicle epithelial progenitor cells, suggesting potential in anti-hirsutism therapy.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

This article reviews the role of microRNAs as epigenetic modulators in dermatology but reports no new clinical findings.

This study found that tannic acid accelerated wound healing in rats by modulating inflammatory cytokines, increasing growth factors, and activating the Erk 1/2 pathway.

This study describes a patient with metastatic renal cell carcinoma who experienced a recurrence of pemphigus vulgaris after receiving interleukin 2 immunotherapy, suggesting a possible link between the treatment and autoimmune disease recurrence.

This review discusses the significance of IL-1 family cytokines in skin inflammation and pathology, emphasizing their interactions with microbes and potential therapeutic applications, but reports no new clinical results.

This study reported that baicalin activates the Wnt/β-catenin signaling pathway in mouse hair follicles, suggesting its potential as a topical treatment for hair loss.

This review discusses how recent studies use models and experiments to understand immune system signaling, but it reports no new clinical findings; the authors suggest strategies for improving these models.

This study found that the small molecule honokiol may protect against inflammation, collagen breakdown, and cell damage caused by cigarette smoke in skin cells cultured in vitro.

This study found that UV-B exposure significantly increased the expression of inflammatory cytokines IL-1β and IL-8 in cultured sebocytes.

This study found that mechlorethamine restored hair growth in mice with alopecia-areata-like disease by eliminating infiltrated lymphocytes and inhibiting certain pro-inflammatory cytokines in treated skin areas.

This review discusses the current medical treatments for hepatocellular carcinoma, noting that while new local therapies show high response rates, their true impact on patient survival is uncertain.

This study found that Trichosanthes kirilowii extract significantly enhances keratinocyte proliferation and wound healing in vitro and in vivo, suggesting its potential as a wound-healing component.

This review explores the role of neutrophil recruitment in the inflammation seen in hidradenitis suppurativa and emphasizes potential therapeutic targets within these pathways, but it reports no new clinical results.

This review summarizes recent research on alopecia areata, highlighting advances in targeted therapies due to improved understanding of its immunopathogenesis, though it reports no new clinical results.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

This study identifies KLK14 as a significant factor contributing to hair defects and skin inflammation in a mouse model of Netherton syndrome.

This review discusses the application and potential of baricitinib, a JAK1/2 inhibitor, for treating dermatological diseases like alopecia areata and reports no new clinical results.

This study found that alopecia areata patients had higher baseline interleukin levels, which significantly decreased with tofacitinib treatment, though this change did not correspond to disease severity improvement.

This study found that procyanidin oligomers from apples and barley may stimulate hair growth by promoting hair epithelial cell proliferation and protecting them from apoptosis via MEK activation in a murine model.

This case report describes a patient with psoriasis who experienced scalp hair darkening and increased growth during anti–IL-17 therapy.

In this study, rabies virus antigens were detected in the outer root sheath of the follicle-sinus complex in the muzzle skin of rabid dogs, suggesting its usefulness as an alternative diagnostic specimen.
