Evolving cognition of the JAK-STAT signaling pathway: autoimmune disorders and cancer

Signal Transduction and Targeted Therapy, Journal Year: 2023, Volume and Issue: 8(1)

Published: May 19, 2023

Abstract The Janus kinase (JAK) signal transducer and activator of transcription (JAK-STAT) pathway is an evolutionarily conserved mechanism transmembrane transduction that enables cells to communicate with the exterior environment. Various cytokines, interferons, growth factors, other specific molecules activate JAK-STAT signaling drive a series physiological pathological processes, including proliferation, metabolism, immune response, inflammation, malignancy. Dysregulated related genetic mutations are strongly associated activation cancer progression. Insights into structures functions have led development approval diverse drugs for clinical treatment diseases. Currently, been developed mainly target commonly divided three subtypes: cytokine or receptor antibodies, JAK inhibitors, STAT inhibitors. And novel agents also continue be tested in preclinical studies. effectiveness safety each kind drug warrant further scientific trials before put being applications. Here, we review current understanding fundamental composition function pathway. We discuss advancements JAK-STAT–related pathogenic mechanisms; targeted therapies various diseases, especially disorders, cancers; newly inhibitors; challenges directions field.

JAK-STAT pathway inhibitors in dermatology

Anais Brasileiros de Dermatologia, Journal Year: 2023, Volume and Issue: 98(5), P. 656 - 677

Published: May 23, 2023

The JAK-STAT signaling pathway mediates important cellular processes such as immune response, carcinogenesis, cell differentiation, division and death. Therefore, drugs that interfere with different patterns have potential indications for various medical conditions. main dermatological targets of inhibitors are inflammatory or autoimmune diseases psoriasis, vitiligo, atopic dermatitis alopecia areata; however, several dermatoses under investigation to expand this list indications. As should gradually occupy a relevant space in prescriptions, review presents the available drugs, their immunological effects, pharmacological characteristics, related clinical efficacy safety, aiming validate best practice.

Atopic dermatitis (AD) is a recurrent, chronic, inflammatory, itchy skin disorder that affects up to 20% of the pediatric population and 10% adult worldwide. Onset typically occurs early in life, although cardinal disease features are similar across all ages, different age groups ethnicities present distinct clinical characteristics. The imposes significant burden health-related quality life domains, both children adults, substantial economic cost at individual national levels. pathophysiology AD includes complex multifaceted interplay between impaired dysfunctional epidermal barrier, genetic predisposition, environmental contributors, such as chemical and/or biological pollutants allergens, context dysregulated TH2 TH17 skewed immune response.
