The generation of MVP in response to UVB involves the Platelet-activating factor receptor (PAFR) and the enzyme acid sphingomyelinase (aSMase). As UVB generates some cytokines such as interleukin-8 (IL-8) in a PAFR-dependent manner, one question is if the production and release of IL-8 and MVP could be linked. Using the human keratinocyte-derived cell line HaCaT, the present in vitro studies indicate that pretreatment of HaCaT keratinocytes with PAFR agonist ester can synergize with low fluences of UVB to generate high levels of MVP as well as IL-8 protein. Treatment of cells with an aSMase pharmacologic inhibitor blocked both processes. These studies indicate the possibility that MVP could be involved in pathologic processes involving UVB-generated production of pro-inflammatory cytokines such as IL-8.</p>","PeriodicalId":73660,"journal":{"name":"Journal of clinical and investigative dermatology","volume":"9 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8693786/pdf/nihms-1764321.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39636600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serum amyloid A (SAA) is a conserved acute phase protein in response to trauma, infection, malignancy, and severe stress. SAA may have a homeostatic role rather than a pro-inflammatory or anti-inflammatory one. Serum levels of SAA were demonstrated to be raised in several inflammatory systemic and skin diseases as rheumatoid arthritis, systemic lupus erythematosus, and psoriasis. Aim: This study aimed to evaluate serum levels of SAA, and IL 6 in a sample of Egyptian LP patients and to estimate its correlation with disease severity. Patients and methods: We included 21 adult patients with LP and 21 healthy adults as control. The total score of LP severity was measured for all patients through measurement of the affected body surface area in cutaneous LP patients while using a semi-quantitative clinical scoring system for oral LP together with the visual analog scale for pain assessment in OLP. Serum levels of SAA were estimated in all participants using enzyme-linked immunosorbent assay. Results: The expression levels of SAA and IL 6 in peripheral blood of patients in the two groups were detected. Pearson analysis was used in the correlation between SAA and IL 6 and Receiver operating characteristic (ROC) curve was employd to analyze the predictive value of SAA and IL 6 for LP severity. Logistic regression analysis was used to analyze the risk factors of LP patients. The expression levels of SAA and IL 6 of patients in sever form were significantly higher than those in mild form (P<0.05). Pearson analysis showed that SAA was positively correlated with IL 6 expression (P<0.05). ROC curve analysis showed that AUC predicted by SAA and IL 6 for LP severity was 0.789 and 0.762 (P<0.05). Logistic regression analysis showed that SAA and IL 6 were prediction indexes of LP severity. Conclusion: The levels of SAA and IL 6 were significantly increased during LP and effectively predicted the severity of LP and is a risk factor affecting LP patients. Further studies are needed to establish this association then it might be used for the evaluation of therapeutic outcomes.

Immunosuppression is also associated with unique mutagenic stressors that likely contribute to cSCC pathogenesis. However, it is unknown whether these stressors contribute to a distinct mutation profile that may drive disease progression. This review was conducted to assess the mutational landscape of cSCC arising in immunosuppressed hosts. Specifically, we sought to determine gene mutation frequencies in immunosuppressed cSCC. An electronic search was performed in PubMed, Embase, Scopus, and Cochrane databases. Studies performing DNA sequencing or genotyping of cSCC were identified. Studies were excluded if the immune status of each tumor was not available. Eighteen studies met inclusion criteria. Due to study heterogeneity a meta-analysis was unable to be performed. However, statistical analysis was performed on the most frequently reported genes. NOTCH1 was the most frequently mutated gene in immunosuppressed cSCC, and was significantly higher than immunocompetent cSCC after multiple comparison adjustment (77.7 versus 58.1%, OR 2.50, 95% CI 1.40-4.46, p=0.002). No other statistically significant differences were observed. Our results suggest that NOTCH1 mutations are more common in cSCC arising in immunosuppressed hosts. Several prior observations reviewed here further support a role for NOTCH1 in immunosuppressed cSCC, however larger studies are needed to confirm our findings.
