Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by cognitive impairments that might be accompanied by declines in activities of daily living, neuropsychiatric disorders and a loss of motor function [1,2]. At present, the prevalence of dementia of Alzheimer’s type (DAT) is approximately 4% among elderly people [3]. With the increase in the aging the population, the number of individuals with DAT is still increasing.

An ancient proverb like “we are what we eat”, entails the significance and an influence of dietary habits and thereby nutrients on all living beings. A universal system encompasses various categories of classes that recognize consequences of various diets on immunity and thereby on the health of an individual. These mechanisms mainly consist of epigenetic machineries, metabolic pathways, circadian rhythms, and diet-responsive effectors. In this light, various clinical studies exhibit immune-modulatory and beneficial effects of interceding nutrients on various diseases.

The ongoing global Coronavirus Disease 2019 (COVID19) pandemic has enormous social and economic impact. COVID19 is caused by the Coronavirus Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and is characterized by a high transmission rate and increased mortality from acute respiratory distress syndrome compared to other viruses.

Epigenetics is the study of heritable modifications to gene expression, such as DNA methylation, histone modifications, and RNA modifications, that do not alter the nucleotide sequence of the corresponding gene. Recently, RNA modification has emerged as a novel research focus. We have detected over 170 different RNA modifications,  such as N6-methyladenosine (m6A), N7-methylguanosine (m7G), 5-methylcytosine (m5C), N1-methyladenosine (m1A), N3-methylcytosine (m3C), and pseudouridine (ψ).These modifications are important for biological processes like RNA metabolism and post-transcriptional regulation. 

The skeletal system consists mostly of extracellular matrix and mineral salts. Osteoblasts and chondrocytes create enormous amounts of extracellular matrix proteins for skeletal systems to grow and sustain. Many skeletal metabolism related proteins are produced by endoplasmic reticulum (ER) and secrete outside cell membrane then form to extracellular oligometric matrix proteins and collagens.
