    TLDR Sebaceous glands play a key role in skin health, immunity, and various skin diseases.
    The document reviews the multifaceted role of sebaceous glands (SG) in skin health, termed "sebaceous immunobiology," highlighting their contributions to skin homeostasis, innate immunity, and the pathophysiology of various skin diseases. It emphasizes the importance of sebaceous lipids in skin immunity, with sebocytes acting as immune regulators and expressing inflammatory mediators that influence T cell polarization. The review also discusses the gland's role in hair follicle morphogenesis and how immune cells regulate SG function. Advances in stem cell and sebocyte models have improved our understanding of SG physiology and the control mechanisms of sebocyte function. The complex regulation of sebocyte-induced immunological reactions by factors like sex steroids and endocannabinoids is linked to skin diseases such as acne, atopic dermatitis, and hair diseases. The document also explores the immunological aspects of SGs, including their role in the immune response to bacterial antigens and the production of antimicrobial peptides. It touches on the in situ production and action of sex steroids in SG physiology and pathology, the importance of transcription factors like NGFI-B and GATA6, and the role of peroxisome proliferator-activated receptor gamma (PPARγ) in SG function and as a potential therapeutic target for SG-related inflammatory skin diseases. Lastly, it describes the SG's involvement in hair follicle regulation and scarring alopecia, and its potential as a target for future therapeutic developments.

      in Research  692 upvotes 4 months ago
      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      in Research/Science  43 upvotes 3 months ago
      Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.

      in Research/Science  62 upvotes 1 year ago
      Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

      Dutasteride has been used for 20 years with some hair thickness improvement but no dramatic regrowth. The user also experimented with minoxidil, tretinoin, and peptides like BPC 157 for potential benefits in hair density and quality.
