The document discussed the role of lipid droplets (LDs) and associated proteins in sebocytes, the cells in sebaceous glands responsible for lipid production. It highlighted the importance of proteins like histone H3, perilipins (PLIN1 to PLIN5), and the CIDE family (CIDEA, CIDEB, CIDEC) in lipid metabolism and storage. The studies revealed that deficiencies in CIDE proteins led to decreased triglyceride storage and increased lipolysis, causing lean phenotypes. However, research was limited by inadequate in vitro models for sebaceous differentiation, as current cell lines do not fully replicate the three-dimensional structure of sebaceous glands in vivo.

research Deciphering the Functions of the Hair Follicle Infundibulum in Skin Physiology and Disease

38 citations , September 2014 in “Cell and Tissue Research”

This review explores the infundibulum's role and importance in skin diseases and emphasizes the need for further research into its biology and potential therapeutic targeting, but it presents no new findings.

research Cidea Control of Lipid Storage and Secretion in Mouse and Human Sebaceous Glands

36 citations , March 2014 in “Molecular and Cellular Biology”

This study found that Cidea is critical for regulating lipid storage and sebum secretion in sebaceous glands, with its deficiency causing hair issues and impaired skin functions in mice.

research Keratin 79 Identifies a Novel Population of Migratory Epithelial Cells That Initiates Hair Canal Morphogenesis and Regeneration

60 citations , November 2013 in “Development”

This study found that the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.
