AI Article Synopsis

  • Atopic dermatitis (AD) is a recurring skin condition primarily driven by inflammation from T-helper 2 cells, and recent research suggests that JAK inhibitors like momelotinib (MMB) could help treat it.
  • In experiments with AD mice and activated dendritic cells, topical application of MMB showed significant improvements, including reduced skin severity, lower total serum IgE, and better histological metrics.
  • MMB also decreased the expression of various pro-inflammatory markers and inhibited certain signaling pathways, indicating its potential as a new effective treatment strategy for managing AD symptoms.

Article Abstract

Atopic dermatitis (AD) is a chronic recurrent skin disease dominated by T-helper 2 inflammation. Momelotinib (MMB) is a novel JAK1/JAK2 inhibitor suppressing the signal transduction of multiple pro-inflammatory cytokines. Recent studies indicated that JAK inhibitor could play a therapeutic role in AD disease. In this study, we evaluated the efficacy of MMB as a novel JAK1/JAK2 inhibitor in DNCB-induced AD mice and TSLP-activated dendritic cells. Our data showed that topical application of MMB reduced the skin severity scores and total serum IgE levels, and alleviated the histological indexes including epidermal thickness measurement and mast cell number. Also, it was demonstrated that MMB down-regulated the mRNA expression of IL-4, IL-5, IFN-γ and TSLP, and inhibited the phosphorylation of STAT1, STAT3 and STAT5 in skin lesions. Moreover, MMB reduced the expression of CD80, CD86, MHCII and mRNA of OX40L in TSLP-activated dendritic cells. In general, our study suggests that MMB can improve the symptoms of AD and topical application of MMB can become a promising new therapy strategy for AD.

This study investigated the chemopreventive mechanisms of fish oil (FO) at different doses and administration routes in skin carcinogenesis induced by 7,12-dimethylbenz[a]anthracene (DMBA) and croton oil (CO) in Swiss albino mice. Seventy mice were divided into 10 groups, including controls and those receiving FO either orally or topically, with or without the carcinogenesis protocol. Warts were morphologically analyzed.

: Since 2008, following clinical studies conducted on children that revealed the ability of the β-adrenergic antagonist propranolol to inhibit capillary growth in infantile hemangiomas (IHs), its oral administration has become the first-line treatment for IHs. Although oral propranolol therapy at a dosage of 3 mg/kg/die is effective, it can cause systemic adverse reactions. This therapy is not necessarily applicable to all patients.

Psoriasis, a chronic inflammatory dermatosis, represents a significant clinical challenge due to its complex pathogenesis and the limitations of existing therapeutic strategies. Current psoriasis diagnoses are primarily clinician-dependent, with instrumental diagnostics serving as adjuncts. Ongoing research is progressively deciphering its molecular underpinnings; the future of psoriasis diagnostics may involve genetic and immunological profiling to pinpoint biomarkers, enabling more accurate and timely interventions.

: This study aimed to evaluate the safety and efficacy of chitosan-based bioadhesive films for facilitating the topical delivery of curcumin in skin cancer treatment, addressing the pharmacokinetic limitations associated with oral administration. : The films, which incorporated curcumin, were formulated using varying proportions of chitosan, polyvinyl alcohol, Poloxamer 407, and propylene glycol. These films were assessed for stability, drug release, in vitro skin permeation, cell viability (with and without radiotherapy), and skin irritation.
