Effects of mycoplasma infection on the host organism response via p53/NF-κB signaling
Abstract
Mycoplasmas are bacteria lacking the cell wall, which is the major characteristic of this taxonomic class (Mollicutes). Among bacteria, mycoplasmas possess the smallest genome known for free-living organisms. This feature limits the autonomy of bacteria and makes them increasingly susceptible to changes in the host organism. Many mycoplasmas themselves cause pathological changes in the host organism, often complicated by immune disorders. Infection with certain strains of mycoplasma results in the activation of the nuclear factor kappa-light-chain-enhancer of activated B cells, which is the major mediator of the inflammatory response. Furthermore, mycoplasmas can inhibit p53-mediated checkpoint control of cell cycle and apoptosis. Collectively, these properties indicate that mycoplasmas might act as cancer-promoting factors. In this review, we summarize the information known to date on the role of mycoplasmas in the regulation of the host immune response and their functional interactions with p53.

CREs: Gene & Cell Therapy
Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.
Apoptosis
Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
Cell Checkpoints & Regulators
Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.
