Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

2.2K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Chromatin Modification in iPS Cells

1.6K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

Forced Transdifferentiation01:28

Forced Transdifferentiation

1.9K
Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.

Summary
This summary is machine-generated.

Macrophages reprogram metabolism and post-translational modifications (PTMs) to respond to stimuli and change function. Altered metabolites, including glucose, lipids, and amino acids, critically influence macrophage polarization via PTMs.

Area of Science:

  • Immunology
  • Metabolic pathways
  • Cellular biology

Background:

  • Macrophages are key immune cells that polarize into distinct phenotypes.
  • This polarization involves significant metabolic and epigenetic changes.
  • Post-translational modifications (PTMs) are crucial for regulating macrophage function.

Purpose of the Study:

  • To review how altered metabolites influence macrophage polarization.
  • To examine the role of PTMs in metabolic reprogramming of macrophages.
  • To understand the impact of metabolite-driven PTMs on macrophage-associated diseases.

Main Methods:

  • Literature review of studies on macrophage polarization.
  • Analysis of metabolic pathways (glucose, lipids, amino acids) in macrophages.
  • Examination of epigenetic and PTMs in macrophage polarization.

Main Results:

  • Metabolic reprogramming, including changes in glucose, lipid, and amino acid metabolism, is central to macrophage polarization.
  • Dynamic PTMs are modulated by microenvironmental metabolites, dictating macrophage responses.
  • Aberrant metabolites and their PTM effects contribute to disease progression in macrophage-associated conditions.

Conclusions:

  • Metabolites significantly shape macrophage signaling and metabolism through PTMs during polarization.
  • Understanding these metabolite-PTM interactions is vital for targeting macrophage function in diseases.
