Background: The aim of this meta-analysis was to analyze all available data from studies investigating associations between polymorphisms in genes responsible for innate immunity and neonatal sepsis development.
Methods: A comprehensive literature search, reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-S guidelines, was performed with no language restriction. Studies derived using the PICO (population, intervention, comparison and outcomes) strategy, with data on the genotype distribution for innate immunity gene polymorphisms in newborns with and without sepsis. Data were analyzed using Review Manager. The Cochran-Mantel-Haenszel test was used to calculate odds ratios with 95% confidence intervals. Heterogeneity was tested using the I index.
Results: From a total of 9428 possibly relevant articles, 33 qualified for inclusion in this systematic review. According to the STrengthening the REporting of Genetic Association Studies, 23 studies were found to be of moderate quality, while 10 were of low quality. The results showed an association of the mannose-binding lectin (MBL) exon 1 genetic polymorphism with the risk of culture-proven sepsis. Toll-like receptor (TLR) 4 rs4986791 genotype distribution suggests its association with the increased risk of culture-proven sepsis. The certainty of evidence per GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) varied from very low to low. Publication bias was not detected.
Conclusions: Out of the 11 investigated single-nucleotide polymorphisms, this meta-analysis found a possible association between the risk for culture-proven sepsis and MBL exon 1 and TLR4 rs4986791 polymorphisms. There is an evident need for larger well-designed, multicentric observational studies investigating inflammatory gene polymorphisms in neonatal sepsis.

Adenosine-to-inosine (A-to-I) editing, catalyzed by adenosine deaminases acting on RNA (ADARs), is a prevalent post-transcriptional modification that is vital for numerous biological functions. Given that this modification impacts global gene expression, RNA localization, and innate cellular immunity, dysregulation of A-to-I editing has unsurprisingly been linked to a variety of cancers and other diseases. However, our current understanding of the underpinning mechanisms that connect dysregulated A-to-I editing and disease processes remains limited.

Adenosine deaminases acting on RNAs (ADARs) are a class of RNA editing enzymes found in metazoa that catalyze the hydrolytic deamination of adenosine to inosine in duplexed RNA. Inosine is a nucleotide that can base pair with cytidine, therefore, inosine is interpreted by cellular processes as guanosine. ADARs are functionally important in RNA recoding events, RNA structure modulation, innate immunity, and can be harnessed for therapeutically-driven base editing to treat genetic disorders.

Adenosine-to-inosine (A-to-I) editing, is a highly prevalent posttranscriptional modification of RNA, mediated by the adenosine deaminases acting on RNA (ADAR) proteins. Mammalian transcriptomes contain tens of thousands to millions of A-to-I editing events. Mutations in ADAR can result in rare autoinflammatory disorders such as Aicardi-Goutières syndrome (AGS) through to irreversible conditions such as motor neuron disease, amyotrophic lateral sclerosis (ALS).

Macrophages play crucial roles in regulating both homeostatic and inflammatory responses, with classical activated (M1) and alternatively activated (M2) subsets defined by the surrounding micro-environment. Renal fibrosis, developed from persistent inflammation, is worsened by M2 macrophages, yet the precise mechanisms underlying macrophage M2 polarization remain unclear. In this study, we investigated the role of Kv1.

Reference values for the non-specific immune response of stickleback have been developed to better understand the natural variability of the immunomarkers and to increase their relevance for the detection of environmental perturbations. However, under field conditions, temperature and salinity can vary from station to station and their influence on the reference ranges of the immunomarkers should therefore be quantified. To this end, adult sticklebacks were exposed either to different temperatures (from 12 to 18 °C) or to different salinities (from 0 to 30 g/L) for 21 days after 10 days of acclimatization.
