Endocannabinoids enhance lipid synthesis and apoptosis of human sebocytes via cannabinoid receptor‐2‐mediated signaling
Abstract
We had previously shown that both locally produced endocannabinoids and exocannabinoids, via cannabinoid receptor‐1 (CB1), are powerful inhibitors of human hair growth. To further investigate the role of the cannabinoid system in pilosebaceous unit biology, we have explored in the current study whether and how endocannabinoids have an impact on human sebaceous gland biology, using human SZ95 sebocytes as cell culture model. Here, we provide the first evidence that SZ95 sebocytes express CB2 but not CB1. Also, prototypic endocannabinoids (arachidonoyl ethanolamide/anandamide, 2‐arachidonoyl glycerol) are present in SZ95 sebocytes and dose‐dependently induce lipid production and (chiefly apoptosis‐driven) cell death. Endocannabinoids also up‐regulate the expression of key genes involved in lipid synthesis ( e.g. , PPAR transcription factors and some of their target genes). These actions are selectively mediated by CB2‐coupled signaling involving the MAPK pathway, as revealed by specific agonists/antagonists and by RNA interference. Because cells with “silenced” CB2 exhibited significantly suppressed basal lipid production, our results collectively suggest that human sebocytes utilize a paracrine‐autocrine, endogenously active, CB2‐mediated endocannabinoid signaling system for positively regulating lipid production and cell death. CB2 antagonists or agonists therefore deserve to be explored in the management of skin disorders characterized by sebaceous gland dysfunctions ( e.g. , acne vulgaris, seborrhea, dry skin).—Dobrosi, N., Tóth, B.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
