At present, there is no reliable biomarker for the diagnosis of traumatic brain injury (TBI). Studies have shown that extracellular vesicles released by damaged cells into biological fluids can be used as potential biomarkers for diagnosis of TBI and evaluation of TBI severity. We hypothesize that the genetic profile of salivary extracellular vesicles in patients with head trauma differs from that in uninjured subjects. Findings from this hypothesis would help investigate the severity of TBI. This study included 19 subjects, consisting of seven healthy controls who denied history of head trauma, six patients diagnosed with concussion injury from an outpatient concussion clinic, and six patients with TBI who received treatment in the emergency department within 24 hours after injury. Real-time PCR analysis of salivary extracellular vesicles in participants was performed using TaqMan Human Inflammation array. Gene expression analysis revealed nine upregulated genes in emergency department patients (LOX5, ANXA3, CASP1, IL2RG, ITGAM, ITGB2, LTA4H, MAPK14, and TNFRSF1A) and 13 upregulated genes in concussion clinic patients compared with healthy participants (ADRB1, ADRB2, BDKRB1, HRH1, HRH2, LTB4R2, LTB4R, PTAFR, CYSLTR1, CES1, KLK1, MC2R, and PTGER3). Each patient group had a unique profile. Comparison between groups showed that 15 inflammation-related genes had significant expression change. Our results indicate that inflammation biomarkers can be used for diagnosis of TBI and evaluation of disease severity. This study was approved by the Institutional Review Board on December 18, 2015 (approval No. 0078-12) and on June 9, 2016 (approval No. 4093-16).

Background: Viral infection causes asthma exacerbations and airway hyperreactivity. Toll-like receptor 3 (TLR3) recognizes double-stranded RNA (dsRNA) of viral or synthetic origin in a fashion different from protein kinase R (PKR). The aim of this study was to examine the expression and function of TLR3 in human airway smooth muscle (ASM) cells. Methods: Expression of TLR3 and muscarinic receptor (MR), histamine receptor (HR), and cysteinyl leukotriene receptor (CysLTR) subtypes was analyzed by quantitative real-time PCR, flow cytometry, or Western blotting. It was assessed whether ASM cells respond to polyinosinic-polycytidylic acid (poly I:C), a synthetic analog of dsRNA, with alterations in M2R, M3R, H1R, and CysLT1R expression. The function of these subtypes was evaluated by cholinergic regulation of forskolin-stimulated cyclic AMP accumulation or by mobilization of intracellular calcium upon stimulation. Results: ASM cells expressed TLR3 and PKR, and intracellular TLR3 expression was demonstrated. Poly I:C caused decreased M2R and increased M3R expression, without affecting H1R and CysLT1R expression. Poly I:C-treated cells showed decreased cholinergic inhibition of forskolin-stimulated cyclic AMP accumulation and enhanced calcium flux in response to acetylcholine, but not to histamine and LTD4. These modulating effects of poly I:C were reversed by chloroquine, but not by 2-aminopurine. Conclusions: The data indicate that poly I:C internalized by ASM cells differentially regulates M2R and M3R expression and function by interacting with TLR3 rather than with PKR, suggesting that these changes may contribute to airway hyperreactivity.

Genetic mechanism of aspirin-induced urticaria/angioedema

PURPOSE OF REVIEWAspirin-induced urticaria/angioedema is a major aspirin-related hypersensitivity often associated with aspirin-intolerant asthma. Genetic studies on aspirin-intolerant asthma have shown chronic overproduction of cysteinyl leukotrienes. The genetic analysis of aspirin-induced urticaria/angioedema is limited, however.RECENT FINDINGSA recent study on HLA genotypes has suggested that the HLA alleles DRB11302 and DQB10609 may be genetic markers for aspirin-induced urticaria/angioedema. A polymorphism study that examined nine single-nucleotide polymorphisms of five leukotriene-related genes [ALOX5 (encoding 5-lipoxygenase), ALOX5AP (5-lipoxygenase-activating protein), PTGS2 (cyclooxygenase 2), LTC4S (leukotriene C4 synthase), and CYSLTR1 (cysteinyl leukotriene receptor 1)] found that promoter polymorphisms of ALOX5 (-1708A>G) and CYSLTR1 (-634C>T) were significantly different between aspirin-intolerant asthma and aspirin-induced urticaria/angioedema, suggesting different contributions to the lipoxygenase pathway. A second polymorphism study, conducted on histamine-related genes, did not find any significant associations with aspirin-induced urticaria/angioedema for the genes HNMT (encoding histamine N-methyltransferase), HRH1 or HRH2 (encoding histamine receptor types 1 and 2 respectively), or the gene encoding high-affinity IgE receptor Ibeta (FcepsilonRIbeta); however, the FcepsilonRIalpha gene promoter polymorphism was significantly associated with aspirin-induced urticaria/angioedema. This finding has been supported by in vitro functional studies.SUMMARYThe HLA alleles DRB11302 and DQB10609, and the ALOX5 and FcepsilonRIalpha promoter polymorphisms, may contribute to the pathogenesis of aspirin-induced urticaria/angioedema. Further investigation to identify candidate genetic markers would help to elucidate the pathogenic mechanism of this condition.
