Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

5.2K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.1K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

1.3K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Connective Tissue Cell Types01:22

Connective Tissue Cell Types

3.2K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

G Protein-coupled Receptors01:15

G Protein-coupled Receptors

12.0K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

6.8K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Summary
This summary is machine-generated.

COVID-19 impacts vitamin D receptor (VDR) and aryl hydrocarbon receptor (AhR) pathways differently based on disease severity. Vitamin D substitution combined with antivirals may improve COVID-19 outcomes.

Area of Science:

  • Immunology
  • Molecular Biology
  • Virology

Background:

  • Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) impacts immune pathways, including the vitamin D receptor (VDR) and aryl hydrocarbon receptor (AhR).
  • Understanding these pathway alterations is crucial for managing COVID-19 severity.

Purpose of the Study:

  • To evaluate the VDR and AhR pathways in the blood of COVID-19 patients.
  • To correlate pathway activity with COVID-19 disease severity.

Main Methods:

  • Observational, single-center, case-control study.
  • Analysis of 240 samples from COVID-19 patients and controls with other respiratory infections (ORIs).
  • Measurement of VDR-specific mRNA and 25(OH)-vitamin D3 levels.

Main Results:

  • VDR mRNA was significantly upregulated in mild COVID-19 cases compared to ORIs.
  • Critically ill patients showed impaired VDR upregulation, with downregulation compared to survivors.
  • No significant difference in 25(OH)-vitamin D3 levels was observed between critically ill patients based on survival.

Conclusions:

  • VDR and AhR pathways are distinctly regulated in COVID-19 patients, varying with disease severity.
  • Investigating a combination therapy of antiviral drugs and vitamin D substitution may offer improved COVID-19 prognosis.
