There was a statistically significant relationship between both null combination of the GSTM1 and GSTT1 genotype polymorphisms and rosacea (P=0.003, OR [95% CI]: 4.18 [1.57-11.13]).

Skin sample analysis showed a higher expression of genes encoding pro-inflammatory cytokines (Il-8, Il-1b, TNF-a) and inflammasome-related genes (NALP-3 and CASP-1) in rosacea, especially PPR.

Exploratory immunohistochemical analysis of HLA-DRA and BTNL2 expression in papulopustular rosacea lesions from six individuals, including one with the rs763035 variant, revealed staining in the perifollicular inflammatory infiltrate of rosacea for both proteins.

In addition, three HLA alleles, all MHC class II proteins, were significantly associated with rosacea in the discovery group and confirmed in the replication group: HLA-DRB1*03:01 (P=1.0 × 10(-8) discovery group; P=4.4 × 10(-6) replication group), HLA-DQB1*02:01 (P=1.3 × 10(-8) discovery group; P=7.2 × 10(-6) replication group), and HLA-DQA1*05:01 (P=1.4 × 10(-8) discovery group; P=7.6 × 10(-6) replication group).

Enhanced ER stress/S1P signalling in rosacea appears to compensate for insufficient VDR-dependent CAMP expression, maintaining adequate CAMP levels during UV-deficient winter to combat life-threatening microbial infections, such as lupus vulgaris.
However, RF treatment led to a significantly greater decrease in papulopustular lesion count and rosacea severity score in PPR compared with PDL treatment.
In vitro and in vivo data indicated that the combination of trans-t-butylcyclohexanol and licochalcone A is an effective combination for alleviating the increased sensitivity of rosacea subtype I.</p> <p>OBJECTIVE: Objective of this open dermocosmetic study was to investigate the efficacy and tolerability of a skin care product containing the anti-inflammatory licochalcone A and the TRPV1 antagonist trans-t-butylcyclohexanol in subjects with sensitive skin prone to redness and rosacea.</p> <p>METHODS: 1221 subjects with sensitive skin and rosacea stage 0-II applied the test product twice daily for 4 weeks.
To evaluate the efficacy, safety, patient satisfaction, and optimal timing of administration of IVM associated with BR (IVM+BR) versus their vehicles in rosacea (investigator global assessment [IGA] ≥3).

Increased expression of MRGPRX2 or enhanced downstream signaling likely contributes to chronic inflammatory diseases such as rosacea, atopic dermatitis, chronic urticaria, and severe asthma.
Long-pulsed 1064-nm neodymium: yttrium-aluminum-garnet laser (LPND) effectively treats rosacea, although the underlying mechanism is unclear, to evaluate the histological effects and molecular mechanism of LPND on LL-37-induced rosacea-like skin lesions in mice.
However, following injury or inflammatory skin diseases such as psoriasis and rosacea, expression of the cathelicidin antimicrobial peptide LL37 breaks tolerance to self-nucleic acids and triggers inflammation.
