Abstract
OBJECTIVE To synthesize the current understanding of RNA-based regulatory mechanisms, focusing on how RNA splicing and non-coding RNAs shape immune responses and airway remodeling in asthma, with the aim of exploring their potential as therapeutic targets for asthma treatment. DATASOURCE Recent advances and emerging research in molecular biology and immunology related to RNA splicing, non-coding RNAs (lncRNAs, circRNAs), and N6-methyladenosine (m6A) RNA methylation in asthma pathogenesis. STUDY SELECTIONS The review incorporates studies highlighting the roles of alternative RNA splicing, non-coding RNAs (lncRNAs and circRNAs), and RNA methylation (m6A) in regulating immune and inflammatory pathways involved in asthma. RESULTS RNA splicing events, non-coding RNAs, and m6A RNA methylation are critical in modulating immune dysregulation, airway remodeling, and inflammation in asthma. These mechanisms influence key inflammatory pathways, mRNA stability, and the overall immune landscape of the disease. CONCLUSION RNA splicing and non-coding RNAs represent promising areas of research for understanding asthma's immune pathology and hold potential as novel therapeutic targets for more effective treatment strategies.

Rosas Mejia O, Claeys TA, Williams A, Zafar A, Robinson RT. IL12RB1 allele bias in human T H cells is regulated by functional SNPs in its 3'UTR. Cytokine 2022; 158:155993. [PMID: 36007427 DOI: 10.1016/j.cyto.2022.155993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 07/25/2022] [Accepted: 08/01/2022] [Indexed: 11/26/2022]
Abstract
Allele bias is an epigenetic mechanism wherein only the maternal- or paternal-derived allele of a gene is preferentially expressed. Allele bias is used by T cells to regulate expression of numerous genes, including those which govern their development and response to cytokines. Here we demonstrate that human TH cell expression of the cytokine receptor gene IL12RB1 is subject to allele bias, and the extent to which this bias occurs is influenced by cells' differentiation status and two polymorphic sites in the IL12RB1 3'UTR. The single nucleotide polymorphisms (SNPs) at these sites, rs3746190 and rs404733, function to increase expression of their encoding allele. Modeling suggests this is due to a stabilizing effect of these SNPs on the predicted mRNA secondary structure. The SNP rs3746190 is also proximal to the predicted binding site of microRNA miR-1277, raising the possibility that miR-1277 cannot exert suppression in the presence of rs3746190. Functional experiments demonstrate, however, that miR-1277 suppression of IL12RB1 3'UTR expression-which itself has not been previously reported-is nevertheless independent of rs3746190. Collectively, these data demonstrate that rs3746190 and rs404733 are functional SNPs which regulate IL12RB1 allele bias in human TH cells.

Abstract
We describe a case of life-threatening disseminated coccidioidomycosis in a previously healthy child. Like most patients with disseminated coccidioidomycosis, this child had no genomic evidence of any known, rare immune disease. However, comprehensive immunologic testing showed exaggerated production of interleukin-4 and reduced production of interferon-γ. Supplementation of antifungal agents with interferon-γ treatment slowed disease progression, and the addition of interleukin-4 and interleukin-13 blockade with dupilumab resulted in rapid resolution of the patient's clinical symptoms. This report shows that blocking of type 2 immune responses can treat infection. This immunomodulatory approach could be used to enhance immune clearance of refractory fungal, mycobacterial, and viral infections.

Abstract
In the present study, we used microRNA (miRNA) sequencing to discover and explore
the expression profiles of known and novel miRNAs in 1000 ng/ml LPS stimulated
for 8 h vis-à-vis non-stimulated (i.e. control) PBMCs isolated from the blood of
healthy pigs. A total of 291 known miRNAs were bio-computationally identified in
porcine PBMCs, and 228 novel miRNAs (not enlisted in the swine mirBase) were
identified. Among these miRNAs, ssc-miR-148a-3p, ssc-let-7g, ssc-let-7f, 3_8760,
ssc-miR-26a, ssc-miR-451, ssc-miR-21, ssc-miR-30d, ssc-miR-99a and ssc-miR-103
were the top 10 most abundant miRNAs in porcine PBMCs. Through miRNA
differential analysis combined with quantitative PCR, we found the expressions
of ssc-miR-122, ssc-miR-129b, ssc-miR-17-5p and ssc-miR-152 were significantly
changed in porcine PBMCs after LPS stimulation. Furthermore, targets prediction
and function analysis indicated a significant enrichment in gene ontology
functional categories related to diseases, immunity and inflammation. In
conclusion, this study on profiling of miRNAs expressed in LPS-stimulated PBMCs
provides an important reference point for future studies on regulatory roles of
miRNAs in porcine immune system.

Trichostatin A, a Histone Deacetylase Inhibitor, Alleviates Eosinophilic Meningitis Induced by Angiostrongylus cantonensis Infection in Mice. Front Microbiol 2019; 10:2280. [PMID: 31636619 PMCID: PMC6787401 DOI: 10.3389/fmicb.2019.02280] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Accepted: 09/18/2019] [Indexed: 12/16/2022] Open
Abstract
Histone deacetylase inhibitor (HDACi) has been used in the treatment of neurodegenerative or autoimmune diseases. Angiostrongyliasis cantonensis caused by Angiostrongylus cantonensis infection is an emerging zoonosis of human eosinophilic meningitis or meningoencephalitis. Progressive neuronal apoptosis is the pathological basis of behavioral dysfunctions in angiostrongyliasis cantonensis. Neurological defects after anthelmintic treatment for angiostrongyliasis cantonensis are still common. In this study, we examined the effects of trichostatin A (TSA), a HDACi, on eosinophilic meningitis induced by A. cantonensis in mice. Intragastric administration of TSA significantly ameliorated brain injury and decreased cognitive impairments in mice at 15 days post-infection. TSA administration effectively reduced the inflammatory factor levels of iNOS, TNF-α, IL-5, IL-6, and IL-13 in infected mice. TSA treatment counteracted apoptosis with reduced expression levels of cleaved caspase-3, -4, -6, and RIP3 in A. cantonensis infected mice. In addition, TSA administration reduced total HDAC activity and increased the acetylation of histone H3 and H4 in the brain tissue of infected mice. The underlying mechanism of TSA on eosinophilic meningitis might be associated with decreased NF-κB p65 nuclear accumulation by inhibiting IκB phosphorylation. Furthermore, a co-expressive network of NF-κB p65 with 22 other genes was constructed according to our previous transcriptomic data in infected mice. We identified the correlations in the gene expression of NF-κB p65 with Lrp10, Il12rb1, Nfkbia, Ube2n, and Ube2d1 in infected mice after TSA administration. Thus, TSA has a protective effect on the progression of eosinophilic meningitis induced by A. cantonensis in mice.

Abstract
BACKGROUND Nontuberculous mycobacteria (NTM) species are a rising threat, especially to patients living with pulmonary comorbidities. Current point-of-care diagnostics fail to adequately identify and differentiate NTM species from Mycobacterium tuberculosis (Mtb). Definitive culture- and molecular-based testing can take weeks to months and requires sending samples out to specialized diagnostic laboratories. METHODS In this proof-of-concept study, we developed an assay based on PCR amplification of 16S ribosomal RNA (rRNA) rrs genes by using universal mycobacterial primers and interrogation of the amplified fragments with a panel of binary deoxyribozyme (BiDz) sensors to enable species-level identification of NTM (BiDz-NTMST). Each BiDz sensor consists of 2 subunits of an RNA-cleaving deoxyribozyme, which form an active deoxyribozyme catalytic core only in the presence of the complimentary target sequence. The target-activated BiDz catalyzes cleavage of a reporter substrate, thus triggering either fluorescent or colorimetric (visually observed) signal depending on the substrate used. The panel included BiDz sensors for differentiation of 6 clinically relevant NTM species (Mycobacterium abscessus, Mycobacterium avium, Mycobacterium intracellulare, Mycobacterium fortuitum, Mycobacterium kansasii, and Mycobacterium gordonae) and Mtb. RESULTS Using the fluorescent BiDz-NTMST assay, we successfully identified the species of 38 clinical isolates. In addition, a subset of strains was tested with visual BiDz sensors, providing proof-of-concept for species typing of NTM by the naked eye. CONCLUSIONS The BiDz-NTMST assay is a novel platform for rapid identification of NTM species. This method is highly specific and significantly faster than current tools and is easily adaptable for onsite diagnostic laboratories in hospitals or clinical laboratories.
