sebaceous gland sebum sebocyte cell-cell junctions cell-matrix junctions skin integrity adhesion proteins differentiation sebum secretion

TLDR Cell junctions are crucial for healthy skin by supporting sebaceous gland function and sebum production.

This document reviews the role of cell-cell and cell-matrix junctional complexes in sebaceous gland (SG) homeostasis and differentiation. It highlights the importance of these junctions in maintaining skin integrity through sebum production, which lubricates and protects the skin and hair. The review notes that while SGs are increasingly studied for their roles in immunomodulation and energy metabolism, the adhesion processes in sebocytes have not been systematically examined. Understanding these processes is crucial, as changes in adhesion-relevant proteins can lead to structural changes in SGs. The document aims to enhance the understanding of sebocyte differentiation and sebum secretion, potentially leading to new therapeutic strategies for skin diseases.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

nkrata in Research 830 upvotes 1 year 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.
