Long noncoding RNAs (lncRNAs) are reported to play critical roles in asthma. However, the function of Opa interacting protein 5-antisense 1 (OIP5-AS1) in pyroptosis during the development of asthma remains unexplored. The blood samples of asthma patients (<i>n</i> = 32) as well as the baseline characteristics of asthma patients or healthy people were collected. An in vivo model of asthma was established using house dust mites (HDM). To mimic asthma in vitro, BEAS-2B cells were treated with HDM. Cell pyroptosis and apoptosis were examined by flow cytometry. The levels of interleukin-1 beta (IL-1β) and interleukin-18 (IL-18) were detected by enzyme-linked immunosorbent assay (ELISA). The binding among messenger RNAs (mRNAs) was assessed by chromatin immunoprecipitation (ChIP), dual luciferase report assay, RNA immunoprecipitation (RIP), co-immunoprecipitation (Co-IP), and RNA pull-down assay, respectively. The cellular localization was observed by fluorescence in situ hybridization (FISH) staining. The level of OIP5-AS1 was upregulated in asthma patients. HDM induced pyroptosis and increased the levels of IL-18, IL-1β, and lactate dehydrogenase (LDH) in BEAS-2B cells, which was obviously reversed by OIP5-AS1 knockdown. Consistently, the expressions of NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), c-caspase 1, and pyroptosis-related gasdermin D-1 (GSDMD-1) in BEAS-2B cells were upregulated by HDM treatment, while these phenomena were partially abolished by silencing of OIP5-AS1. Moreover, HDM promoted the progression of asthma in vivo, which was rescued by the downregulation of OIP5-AS1. OIP5-AS1 silencing decreased HDM-induced cell pyroptosis by inactivation of NLRP3. More importantly, OIP5-AS1 promoted the mRNA stability of yes-associated protein (YAP) via binding with eukaryotic translation initiation factor 4A3 (EIF4A3), and OIP5-AS1 was transcriptionally upregulated by doublesex and mab-3 related transcription factor 3 (DMRT3).

Macrophage enrichment of the tumour microenvironment (TME) is a prognostic factor in DLBCL among immunocompetent people, with some studies reporting that macrophage enrichment predicts a superior response to rituximab therapy. The macrophage phenotype is also important, with reportedly poorer outcomes with enrichment of anti-inflammatory (M2) macrophages. To date, the relationship between the type/number of tumour macrophages and outcomes in HIV-associated DLBCL (HIV-DLBCL) has been poorly explored. In this study, we assessed tumour macrophage numbers in a South African cohort of patients with DLBCL and a high HIV-seropositivity rate. Immunohistochemistry for CD68 and CD163 was performed on the diagnostic biopsies of 79 patients with DLBCL. Relevant information was documented from the clinical records, including disease stage, international-prognostic index score, HIV-related parameters, C-reactive protein, ferritin levels and immune cell numbers (monocytes, lymphocytes and neutrophils). Survival analysis was performed using Kaplan–Meier survival estimates, and the correlation between tumour macrophage numbers and a variety of immunological parameters was assessed using Spearman’s rho. Of the 79 patients included, 87.2% were living with HIV, and rituximab therapy was used in 46.9%.

Optimal antitumor immunity entails a multifaceted interplay involving NK cells, T cells and DCs, orchestrating immune effector functions. Although DC-based vaccines and NK cells' cytotoxic capabilities hold substantial therapeutic potential, their interaction is frequently hindered by immunosuppressive elements such as myeloid-derived suppressor cells (MDSCs) and regulatory T cells. Chemokines and cytokines, such as CXCL12, CCL2, interferons, and interleukins, play crucial roles in modulating NK/DC interactions and enhancing immune responses.

It is now widely demonstrated that oxidative stress (OS) plays an important role in the modulation of the pathogenesis of this disease. Mitochondrial DNA (mtDNA) is highly vulnerable to OS and it is known a decrease of mtDNA copy number in SLE patients. However, to date, it has not been investigated if this decrease is associated with a dysregulation of mitochondrial homeostasis genes. Our aim is to evaluate the amount of mtDNA copy number and the expression of the genes more involved in the mitochondrial homeostasis pathways, in peripheral blood mononuclear cells (PBMCs) of SLE patients and healthy controls. We analysed the amount of mtDNA in PBMCs of 72 SLE patients and 61 healthy controls by qPCR. Then, we investigated the expression variability of TFAM and SIRT1 (biogenesis), MFN1 and MFF (fusion/fission) and PRKN2 (mitophagy) genes in a subgroup of SLE patients and healthy controls. Interestingly, we have observed a highly significant decrease in mtDNA copies in SLE patients compared to healthy controls (P < 0.0001). In addition, we have shown that the expression levels of SIRT1, MFN1 and PRKN2 genes were significantly decreased in SLE patients with respect to healthy controls (P = 0.00001 for SIRT1, P = 0.0150 for MFN1 and P = 0.0009 for PRKN2). Lastly, we have reported a positive correlation between PRKN2 expression level and mtDNA copy number (P = 0.019, r = 0.475). In conclusion, our data confirm the impairment of mtDNA copy number in the disease and show for the first time a dysregulation of the mitochondrial homeostasis genes.
