“…In the liver, vitamin D is converted into 25-OH-D which may then be converted into 1,25dihydroxyvitamin D or calcitriol, the biologically active form of vitamin D, either in the kidneys or by monocyte-macrophages (Adams and Hewison, 2010;Courbebaisse et al, 2010). After the final converting step in the kidneys, calcitriol is released into the circulation as a hormone, then transported to various target organs by binding to vitamin Dbinding protein (VDBP), a carrier protein in the plasma (Tissandié et al, 2006). This hormone regulates the Ca and P levels in the bloodstream and promotes the healthy growth and bone turnover.…”

“…This hormone regulates the Ca and P levels in the bloodstream and promotes the healthy growth and bone turnover. It also affects neuromuscular function and inflammation, and regulates the proliferation, differentiation and apoptosis of cells by modulating the action of many genes (Tissandié et al, 2006).…”

“…One of the most important roles of vitamin D is to maintain skeletal calcium balance by promoting calcium absorption in the intestines (Holick, 2007) and a lack of vitamin D causes rickets in children and exacerbation of osteoporosis and the development of osteomalacia in adults. Moreover, several research showed that vitamin D plays an important role as an agent preventing or delaying the onset of certain autoimmune (diabetes type I) and proliferative diseases (solid cancers, leukemia, psoriasis) (Tissandié et al, 2006). Thus, highlighting physiological role of this hormone justifies its growing interest.…”

The aim of this study was to determine the 25-hydroxyvitamin D3 (25-OH-D3) amounts in meat and serum of the Moroccan one-humped camels. The obtained results showed that the 25-OH-D3 amounts in serum (ng/mL), liver, kidney and muscle (ng/g) were 390±45; 7.071±1.003; 6.154±1.067 and 4.241±1.045 respectively. Values in liver were significantly higher (p< 0.05) than those of muscle. Serum 25-OH-D3 levels in camels were very higher than those of ruminant species. Meat of camel was rich in water and ash, and the amounts of 25-OH-D3 in it's various analyzed tissues were similar to those reported for this constituent in the corresponding tissues of bovine species and slightly higher than those measured in other domestic animals.

Background: The skin, mucosa, and extremities can be affected by lichen planus (LP), a chronic lichenoid inflammatory condition. Rich inflammatory T cells infiltration, which travel in a band-like pattern in the upper section of the dermis, is a characteristic hallmark of LP. There have been numerous descriptions of the disease's various subtypes. Vitamin D regulates immunological function, making it a key factor in the development and progression of LP. Objective: Review of possible role of vitamin D in the pathogenesis of Lichen Planus. Methods: We scoured scholarly papers and databases including PubMed, Google Scholar, and Science Direct for information on Lichen Planus and vitamin D between May 1986 and January 2022, however only the latest or most comprehensive study was considered. The authors also assessed the usefulness of references taken from similar books. Documents written in languages other than English have been overlooked because of a lack of funding to translate them. Unpublished articles, oral talks, conference abstracts, and dissertations were all generally agreed upon to not constitute valid scientific investigation. Conclusion: Vitamin D deficiency reduces Th2 cells and other T cells that are included among inflammation processes like T helper cells 11 and 17. This makes a bad situation much worse in inflammatory disorders like Lichen Planus.

The relationships between nutrition and immunity have been the subject of several studies. The main fact lies in the deep entanglement between immunity, and nutritional state: all deficiencies in proteins, essential fatty acids, metallo-enzymes, vitamin factors, and antioxidant elements lead to a dysfunction of the immune system. On the other hand, some excess food (total lipid intake, type of fatty acids, simple sugars, etc.) can, also, have deleterious effects. The emergence of new infectious diseases with new pathogenic properties is a serious global health problem. Covid-19 infection (Coronavirus Disease-2019) caused by the coronavirus SARS-CoV2 (Severe Acute Respiratory Syndrome Coronavirus-2), is recognized as pandemic by the World Health Organization (WHO).This implies strict prevention measures, and a strategy to be developed throughout good hygiene, healthy and balanced diet, and compliance with the con-finement rules.
