Abstract

hyperglycemia causes a degenerative syndrome that involves an inflammatory process with an increase in certain proinflammatory cytokines and chemokines which in the process will activate B cells to produce immunoglobulins through several mechanisms. One of the interesting mechanisms is the mechanism via the MyD88 pathway. Objectives: to explore the role of MyD88 adapter protein in Toll-like receptor activation and B cell maturation under hyperglycemia conditions. Methods: a literature review was done to answer the study objectives. Results: Class switching process under hyperglycemia conditions involves activation of NFkB through the inflammatory MyD88-dependent pathway to trigger the expression of TLR and B cell maturation and proliferation as well as antibody production. The MyD88 adapter protein is a protein formed by stimulation of pro-inflammatory cytokines IL-6 and plays a role in the continuation of signals from the TLR and IL-1 pathways. Mature B cell stimulation induces 2 genetic changes in the Ig gene locus, called somatic hypermutation (SHM) and class switch recombination (CSR) to produce antibodies. Changes in immunoglobulin genes occur related to changes in certain DNA segments at the locus of genes where CSR occurs, this gene change requires the role of AID (activated-induced cytidine deaminase) in DNA cleavage. AID in mature B cells is activated by proinflammatory cytokines via induction of NfKB activation via the inflammatory MyD88-dependent pathway. Conclusion: Toll-like receptor activation plays a crucial role in B cell maturation activated by pro-inflammatory cytokine via MyD88 dependent-NFkB activation.

Abstract

Toll-like receptors (TLR) are essential to pathogen recognition to activate innate immunity. TLR2, 3, 4, 6, 7, 8, and 9 are involved in immunity to dengue virus. The involvement of TLR9, known to recognize CpG DNA, in dengue virus (DVI) infection, an RNA virus, is unusual. We hypothesize that there is an elevated expression and activation of TLR9 through specific mechanisms in DVI. A scoping review was carried out to collect articles that have been written regarding this topic. Article searches were carried out on the PubMed (Medline), Proquest, EBSCO, and Google Scholar databases with inclusion criteria: articles in the form of research results using human subjects or human cells, conducted from 2013 to 2023, in English, and can be accessed in full -text. Gray articles, books, and review articles were excluded from the study. The literature search results found 821 articles, with eight articles meeting the criteria. Based on mapping, synthesis, and analysis of the articles obtained, it was found that there was increased expression and activation of TLR9 in the DVI due to the release of mtDNA.
