Streptococcus pyogenes infection continues to be a worldwide public health problem causing various diseases in humans, including impetigo and oropharyngeal infections that are responsible for the development of rheumatic fever (RF), a multi-organ inflammatory disorder, Rheumatic heart disease (RHD) is its major sequel that leads to heart valves lesions, clinically classified as regurgitation and/or stenosis.

Neural circuits' role in regulating neurogenesis within the adult subventricular zone (SVZ) of the lateral ventricles (LV) has been extensively studied over the past two decades. The dynamic interplay between neurons, neurotransmitters, and LV neural stem cells (NSCs) highlights the critical influence of neural circuits on NSC renewal, proliferation, and differentiation.

Gastrointestinal stromal tumors are mesenchymal tumors which predominantly originate from the interstitial cells of Cajal in the intestinal lining. Around ~85% of malignant GISTs possess activating mutations in the tyrosine kinase receptors KIT or PDGFRA. The driver mutations in genes other than KIT or PDGFRA account for around 15% GISTs and belong to highly heterogeneous groups called wild-type GISTs. Around 20–40% of WT-GISTS are deficient for the succinate dehydrogenase complex (SDHA, SDHB, SDHC, SDHD). 

CNS myelination is a well-known biological phenomenon related to increase in action potential conduction speed and synaptic integration. Demyelination or abnormal myelination has been related to seizures and epilepsy either in patients or animal models. Although its role in fastening action potential propagation has been confirmed, few additional biological functions of CNS myelin has been described.

Influenza A virus (IAV) and Streptococcus pneumoniae (SPn) are two major respiratory pathogens in humans. IAV infection alone is often self-limited, and SPn colonization can be found in 5-90% of healthy individuals, as normal flora [1,2].
