This study systematically reviewed literature on paradoxical reactions during biologic treatments for psoriasis, identifying immune dysregulation mechanisms and diverse clinical manifestations, highlighting that mild cases often respond well to topical treatments, while severe cases may require switching to different IL-23 inhibitors.

This review reports that psoriatic alopecia, a type of hair loss linked to psoriasis, is difficult to diagnose and often resistant to conventional treatments, highlighting the need for further research into its immune-related mechanisms and personalized treatment approaches for better management.

This study reported that a newly developed hydrogel patch, designed to recruit regulatory T cells through ROS-triggered release of CCL22, improved wound healing and hair follicle regeneration in a diabetic mouse model by scavenging ROS, thereby protecting Tregs and suppressing Th17 cells.

This review discussed the cutaneous manifestations of APECED, highlighting chronic mucocutaneous candidiasis, alopecia areata, and vitiligo, while emphasizing the importance of early detection and monitoring for accurate diagnosis and patient care in various populations.

Increased Treg cells and IL-10 may help quick recovery in acute diffuse and total alopecia.

This article discusses the role of regulatory T cells in alopecia areata, where their deficiency in hair follicles may lead to impaired local immunity and suggests potential therapies like CAR-T reg cells and low-dose IL-2 to alleviate autoimmunity and promote hair regeneration in affected individuals.

This study found that overexpression of miR-1246 in peripheral CD4+ T cells can reduce markers associated with inflammation and T cell activation in severe active alopecia areata, suggesting potential therapeutic benefits.

This study found that skin organoids derived from iPSCs with an HS-associated NCSTN mutation showed defects in hair follicle stem cell differentiation and increased expression of inflammatory proteins related to hidradenitis suppurativa.

This study found that sulfated CCK octapeptide reduces psoriasis-like skin inflammation in mice, suggesting a new pathophysiological role for CCK in regulating epidermal inflammation.

This study highlights that the combination of adapalene and benzoyl peroxide (Epiduo®) is an effective first-line treatment for acne, significantly inhibiting antibiotic-susceptible and antibiotic-resistant P. acnes strains.

This review found that autoimmune damage is a key factor in alopecia areata, noting its comorbidity with other diseases and the potential of Janus kinase inhibitors in treatment.

Genetically repaired stem cells may treat certain genetic diseases, Th17 cells are key in fighting systemic fungal infections, hair loss in AGA is due to progenitor cell loss, and α-synuclein transfer might contribute to Parkinson's disease progression.

This review discusses the potential of targeting Coenzyme A metabolism to restore metabolic balance, reduce chronic inflammation, and enhance immune function, particularly by modulating Vitamin B5 pathways involved in Th17-mediated inflammation and CD8-dependent anti-tumor immunity.

In this study, increased Treg cell activity indicated by IL-10 and IL-15 was identified as a feature of ADTA, distinguishing it from AA and potentially explaining ADTA's more favorable prognosis.

In this study, researchers found that the cell surface protein Lrig1 plays a crucial role in regulating the suppressive function of regulatory T cells, suggesting it as a potential target for treating autoimmune diseases, as evidenced by experiments in mouse models.

This study developed a nanofiber wound dressing combining ciprofloxacin and tetracycline hydrochloride, which demonstrated strong antibacterial activity against E. coli and S. aureus and showed good biocompatibility with human skin fibroblast cells, indicating significant potential for wound healing applications.

This review discusses the similar immune pathways and genetic risk factors of vitiligo and alopecia areata but reports no new clinical findings, emphasizing the potential for shared treatment research.

This review analyzes the interplay between atopic dermatitis and alopecia areata, suggesting that epidermal barrier dysfunction and genetic predispositions exacerbate both conditions through immune responses.

This study demonstrates that T-cell responses in extensive alopecia areata scalp may be aberrantly regulated, with reduced cytokine production but activated phenotype, providing insight into the disease's immune mechanisms.

This review discusses the pathogenesis of alopecia areata, highlighting the role of immune privilege collapse in hair follicles but reports no clinical results.

This case report describes a 23-year-old woman with alopecia areata who developed new central nervous system demyelination after starting tofacitinib therapy; while the drug was associated with this neurological event, causality is not confirmed. The demyelination was reversible upon stopping the medication and administering corticosteroids.

This study found that oral administration of Flammulina velutipes polysaccharide reduced tumor volume and improved survival in mice by modulating macrophage polarization and enhancing antitumor immune responses.

This study found that multicomponent microarray patches for SARS-CoV-2 vaccination produced stronger immune responses and fewer side effects in mice compared to traditional intramuscular injection.

This case report describes a patient with ulcerative colitis who also presented with an atypical clinical aspect of lichen ruber planus, vitiligo, and alopecia areata.

This study found that mouse parents with uveitis may increase their offspring's susceptibility to experimental autoimmune uveitis, affecting immune processes and the severity of the condition.

In this study, botulinum toxin type A injections reduced the severity of treatment-resistant scalp psoriasis in more patients compared to placebo over a 12-week period.

This study reports that tofacitinib, a JAK inhibitor, may stabilize hair loss in patients with classic lichen planopilaris and frontal fibrosing alopecia, though hair regrowth was not robust.

PDE inhibitors, especially PDE4 inhibitors like apremilast, are effective for certain inflammatory skin conditions but have side effects and can be costly.

This review discusses recent advances and ongoing clinical trials in novel therapeutics for alopecia areata, despite the lack of current FDA-approved treatments for severe cases, and reports no new results.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.
