Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

4.4K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Psychoneuroimmunology: Cardiovascular Disease

664
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Hematopoiesis01:21

Hematopoiesis

9.8K
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

4.1K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Area of Science:

  • Hematology
  • Genetics
  • Cardiovascular Medicine

Background:

  • Clonal hematopoiesis (CH) is the expansion of stem cell clones.
  • Clonal hematopoiesis of indeterminate potential (CHIP) involves pre-leukemic mutations.
  • CHIP is associated with both leukemia and non-malignant conditions like cardiovascular disease.

Purpose of the Study:

  • To review current knowledge on CHIP.
  • To explore the association between CHIP, inflammation, and cardiovascular risk.

Main Methods:

  • Literature review of CHIP and its molecular mechanisms.
  • Focus on mutations in DNMT3A, TET2, ASXL1, and JAK2.
  • Analysis of CHIP's role in inflammation and atherosclerosis.

Main Results:

  • CHIP is linked to increased risk of acute myeloid leukemia.
  • CHIP may promote atherosclerosis through proinflammatory immune cells.
  • Mutations in epigenetic regulators and cytokine signaling genes are key in CHIP.

Conclusions:

  • The molecular mechanisms linking CHIP to cardiovascular disease require further elucidation.
  • CHIP-associated inflammation is a significant factor in atherosclerosis progression.
  • Further research is needed to understand CHIP's impact on non-malignant diseases.
