Sebocyte Apoptosis

Molecular classification
Cellular process, Apoptosis
01

Overview

Sebocyte apoptosis is the programmed cell death of sebocytes, specialized epithelial cells in sebaceous glands. This process is essential for holocrine secretion, where mature sebocytes filled with lipids undergo apoptosis to release sebum. It is regulated by pro-apoptotic signals like isotretinoin and FoxO transcription factors and inhibited by survival pathways. Pharmacological modulation of sebocyte apoptosis, particularly with isotretinoin, is a key therapeutic strategy for acne vulgaris by reducing sebum production and gland size.

Other names
Sebaceous cell apoptosisProgrammed cell death of sebocytes
02

Mechanism of action

Induction of sebocyte apoptosis via RAR-dependent and independent mechanisms, upregulation of TRAIL and other pro-apoptotic genes, and reduction of anti-apoptotic Bcl2 expression.
