This review discusses the potential of drugs targeting the JAK/STAT pathway for dermatological diseases and outlines a protocol to assess existing evidence, reporting no new clinical results.

This study found that glioblastoma cancer stem cells avoid immune suppression by downregulating TLR4, and restoring TLR4 signaling may reduce tumor growth and self-renewal.

This study reviewed therapies for alopecia areata and suggests that Janus kinase inhibitors, such as baricitinib and upadacitinib, show promise in treating both alopecia areata and associated immune-mediated inflammatory diseases.

Certain microRNAs may help treat alopecia areata by targeting immune pathways.

This review discusses the causes, diagnosis, and treatment of pediatric alopecia, emphasizing early diagnosis and considering holistic approaches, but reports no new clinical results.

In this study, researchers observed that follicular damage and stem cell loss in frontal fibrosing alopecia may be mediated by immune attacks at the bulge region, suggesting potential for JAK/STAT-targeting treatments to prevent progression.

This study found that patients with alopecia areata, particularly those with severe cases, exhibit significant systemic immune dysregulation, including altered cell communication networks and epigenetic remodeling in immune cells, suggesting potential pathways for therapeutic targeting.

This review highlights the potential for JAK inhibitors to effectively treat inflammatory and autoimmune skin diseases by targeting the JAK-STAT signaling pathway, advocating for an integrated approach to enhance targeted therapy.

Ritlecitinib may help treat alopecia areata by protecting hair follicles.

This study found that JAK1 and JAK3 inhibitors effectively reversed alopecia in a mouse model of AA by reducing skin inflammation, while JAK2 inhibition did not promote hair regrowth.

This study identified PTEN as a key regulator in non-healing venous leg ulcers, suppressing immune responses and lymphangiogenesis, suggesting its potential as a therapeutic target for promoting VLU healing.

Drugmakers are optimistic about targeting the Wnt pathway for new treatments despite past challenges.

This review discusses the role of perifollicular macrophages in hair growth and suggests targeting them could be relevant for managing hair growth disorders, but reports no new results.

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 novel treatment developments targeting the pathomechanics of alopecia areata, such as JAK inhibitors, show promise, although optimal treatment strategies are still under investigation.

In this study, researchers explored the immunological mechanisms involved in alopecia areata and suggested that targeting immune responses, particularly using JAK inhibitors and other immunomodulatory drugs, could help achieve stable remission and improve patients' quality of life.

This study identified a shared gene signature in scarring alopecia subtypes, with increased mast cell presence, suggesting similar treatment approaches may be effective across these hair loss disorders.

This article reviews current and emerging treatments for alopecia areata, emphasizing the need for biomarker-driven patient stratification to optimize therapeutic strategies and reduce potential side effects; it reports no new clinical findings.

This study evaluated 129 patients with androgenetic alopecia and identified an inflammatory pattern of perifollicular infiltration linked to treatment resistance. Targeting both hormonal and immune pathways improved outcomes for 67% of patients, suggesting inflammation may play a role in some cases of stubborn hair loss.

This study identified changes in immune activation, ferroptosis, and structural genes in alopecia areata subtypes, suggesting molecular markers that might help understand disease variability and guide future treatments.

This study found that NK and CD8+ T cell infiltration may drive inflammation in androgenetic alopecia, suggesting that targeting IL-15 signaling could offer a new therapeutic approach for hair regeneration.

This review discusses the potential of JAK inhibitors as a promising treatment strategy for alopecia areata, highlighting their mechanism and recent FDA approval based on clinical trial efficacy.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

This review discusses the mechanisms regulating wound-induced hair-follicle neogenesis and highlights potential treatments, like Wnt signaling activators, for enhancing this process in humans, yet reports no new clinical results.

This review discusses the challenges and opportunities in targeting the hedgehog pathway for aggressive cancers, emphasizing the complexities of treatment resistance, immune response, and the potential of combining immune checkpoint inhibitors with hedgehog pathway inhibitors, but reports no new clinical results.

This review discusses the complex role of immune disturbances and the JAK-STAT pathway in alopecia areata, noting the success of JAK inhibitors in treatment, while highlighting ongoing debates and challenges in targeting other pathways like IL-17 and TNF-α.

In this study, researchers evaluated CS12192, a selective JAK3 inhibitor, in an alopecia areata mouse model and found it reversed hair growth inhibition comparably to baricitinib, with better safety and similar immune-modulating mechanisms.

This study found that inhibiting the PI3Kδ enzyme in murine models of cutaneous chronic graft-versus-host disease (cGVHD) reduced skin scores and fibrosis, prevented pathogenic lymphoid structures, and improved survival, suggesting it as a promising therapeutic approach to address the disease's hypoxic pathophysiology.

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 reports that hair follicles are dynamic neuro-immuno-endocrine organs with intrinsic signaling pathways, which play a crucial role in hair disorders like alopecia. It highlights emerging regenerative approaches targeting these pathways for hair restoration.
