Ribosome Interactions with SARS-CoV-2 and COVID-19 mRNA Vaccine
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the causing pathogen of the unprecedented global Coronavirus Disease 19 (COVID-19) pandemic. Upon infection, the virus manipulates host cellular machinery and ribosomes to synthesize its own proteins for successful replication and to facilitate further infection. SARS-CoV-2 executes a multi-faceted hijacking of the host mRNA translation and cellular protein synthesis. Viral nonstructural proteins (NSPs) interact with a range of different ribosomal states and interfere with mRNA translation. Concurrent mutations on NSPs and spike proteins contribute to the epidemiological success of variants of concern (VOCs). The interactions between ribosomes and SARS-CoV-2 represent attractive targets for the development of antiviral therapeutics and vaccines.

Aβ-Peptide Production and Conformational Behavior
Alzheimer’s disease (AD) is the most common type of neurodegenerative disease in the world. Genetic evidence strongly suggests that aberrant generation, aggregation, and/or clearance of neurotoxic amyloid-β peptides (Aβ) triggers the disease. Aβ accumulates at the points of contact of neurons in ordered cords and fibrils, forming the so-called senile plaques. Aβ isoforms of different lengths are found in healthy human brains regardless of age and appear to play a role in signaling pathways in the brain and to have neuroprotective properties at low concentrations. This entry describes molecular mechanisms of amyloid-β precursor protein processing in AD.

MERTK and AXL in NSCLC
MERTK and AXL are members of the TAM family of receptor tyrosine kinases and are abnormally expressed in 69% and 93% of non-small cell lung cancers (NSCLCs), respectively. Expression of MERTK and/or AXL provides a survival advantage for NSCLC cells and correlates with lymph node metastasis, drug resistance, and disease progression in patients with NSCLC. The TAM receptors on host tumor infiltrating cells also play important roles in the immunosuppressive tumor microenvironment. Thus, MERTK and AXL are attractive biologic targets for NSCLC treatment.

Enhancer Regulation of WNT3A
Upon traumatic brain injury, epigenome reprograms allowing gene expressions for injury response and regeneration. Using chromatin immunoprecipitation-sequencing of histone marks, we identify a novel enhancer region for induced WNT3A transcription during regeneration of injured cortical neurons. An increased mono-methylation of histone H3 at lysine 4 (H3K4me1) modification and a topological transformation of this enhancer and with promoter of WNT3A gene orchestrate the transcription of WNT3A gene during neuronal regeneration.

Anti-Obesity Properties of Polyphenols
The prevalence of obesity has steadily increased around the world over the past three decades. Polyphenols can be considered nutraceuticals and food supplements recommended for different syndromes. Polyphenols are a class of naturally occurring phytochemicals, some of which have been shown to modulate the physiological and molecular pathways involved in energy metabolism. Polyphenols could act in the stimulation of β-oxidation, in the inhibition of the differentiation of adipocytes, in counteracting oxidative stress, etc.

DMARDs–Gut Microbiota Feedback
Evidence suggests that the increase or decrease of microorganism communities has an effect on the production of metabolites that are related with immunomodulatory functions. This review suggests that there is feedback between DMARDs and gut microbiota, based on the evidence that supports that DMARDs favor intestinal dysbiosis, as well as on the evidence that some bacterial genera participate in DMARDs-type xenobiotics’ metabolism and in the production of metabolites with an immunomodulatory effect. This document sets a precedent in which DMARDs-promoted dysbiosis could cause, in time, variability of response to different therapeutic schemes.

Potential of microRNAs to Attenuate Diabetic Kidney Disease
Diabetic Kidney Disease (DKD) is a significant complication of diabetes and primary cause of end-stage renal disease globally. The exact mechanisms underlying DKD remain poorly understood, but multiple factors, including the renin–angiotensin–aldosterone system (RAAS), play a key role in its progression. Aldosterone, a mineralocorticoid steroid hormone, is one of the key components of RAAS and a potential mediator of renal damage and inflammation in DKD. miRNAs, small noncoding RNA molecules, have attracted interest due to their regulatory roles in numerous biological processes. These processes include aldosterone signaling and mineralocorticoid receptor (MR) expression. Numerous miRNAs have been recognized as crucial regulators of aldosterone signaling and MR expression. These miRNAs affect different aspects of the RAAS pathway and subsequent molecular processes, which impact sodium balance, ion transport, and fibrosis regulation.

Role of Neuroinflammation on Migraine
Neurogenic inflammation in migraine is mainly characterized by the release of neuropeptides such as CGRP and substance P from the trigeminal nerve, leading to arterial vasodilation, plasma protein extravasation, and mast cell degranulation. The involvement of these neuropeptides in migraine is evident, and pro-inflammatory cytokines or chemokines may be involved in this series of reactions.

A2B Adenosine Receptors
Adenosine is a signalling molecule which, by activating specific membrane receptors, acts as an important player during brain insults such as ischemia. or demyelinating injuries. Here we review data in the literature describing A2B receptor-mediated effects in preclinical in vitro and in vivo models of cerebral ischemia and myelination that point to A2B receptor ligands as putative therapeutic targets for the still unmet treatment of stroke or demyelinating diseases.

Differential Inhibitors of Aldose Reductase
Aldose reductase, classified within the aldo-keto reductase family as AKR1B1, is an NADPH dependent enzyme that catalyzes the reduction of hydrophilic as well as hydrophobic aldehydes. AKR1B1 is the first enzyme of the so-called polyol pathway that allows the conversion of glucose into sorbitol, which in turn is oxidized to fructose by sorbitol dehydrogenase. The activation of the polyol pathway in hyperglycemic conditions is generally accepted as the event that is responsible for a series of long-term complications of diabetes such as retinopathy, cataract, nephropathy and neuropathy. The role of AKR1B1 in the onset of diabetic complications has made this enzyme the target for the development of molecules capable of inhibiting its activity.

ROR and Melatonin Nuclear Receptor
Retinoic acid-related orphan receptor (ROR) is implicated in modulating a variety of physiological processes, including cerebellar development, lymphoid tissue development, retinal development, bone formation, lipid metabolism, circadian rhythm, oxidative stress, and inflammation suppression. Furthermore, ROR is also a promising therapeutic target for autoimmune diseases, tumours, obesity, diabetes, and other diseases. Melatonin (N-acetyl-5-methoxytryptamine) is an evolutionary molecule found in bacteria, fungi, algae, plants, invertebrates, and vertebrates. It regulates multiple functions that have developed along the evolutionary timescale. In humans, melatonin is pleiotropic [5]. Melatonin modulates sleep-wake rhythms, reproduction, and bone metabolism; it also affects the immune, neurological, cardiovascular, digestive, urinary, and endocrine systems. Moreover, it exhibits anti-inflammatory, antioxidant, anti-infective, and anti-tumour properties while also being a potential therapeutic agent for obesity, cardiovascular diseases, and neurodegenerative disorders. A debate is ongoing on whether ROR is a nuclear receptor of melatonin.
