Chromatin Modification in iPS Cells01:32

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...

Immunological Memory01:23

Immunological Memory

590
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

979
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

Exon Recombination02:32

Exon Recombination

3.6K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon...

Inheritance of Chromatin Structures03:17

Inheritance of Chromatin Structures

6.2K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Epigenetic Regulation01:37

Epigenetic Regulation

3.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
X-chromosome...

Area of Science:

  • Molecular Immunology
  • Epigenetics in Insects
  • Innate Immunity

Background:

  • Insects possess innate immunity that improves with prior antigen exposure (immune priming).

  • Epigenetic modifications, such as DNA/histone changes, are increasingly implicated in modulating insect immune responses.

Purpose of the Study:

  • To review current knowledge on epigenetic mechanisms in insect immune memory.
  • To explore the role of DNA methylation and histone acetylation in insect immunity.
  • To discuss the potential for epigenetic inheritance of immune responses and evolved resistance in insects.

Main Methods:

  • Review of recent experimental evidence and research findings.
  • Analysis of studies focusing on DNA methylation and histone acetylation in insect models.
  • Examination of transgenerational epigenetic inheritance in the context of insect immunity.

Main Results:

  • Epigenetic modifications, including DNA methylation and histone acetylation, can regulate insect immune gene expression.
  • These epigenetic changes are linked to the development and maintenance of insect immune memory.
  • Evidence suggests transgenerational inheritance of epigenetic marks can confer pre-programmed resistance in offspring.

Conclusions:

  • Epigenetic mechanisms are crucial for understanding insect immune priming and memory.
  • DNA methylation and histone acetylation play significant roles in shaping insect immunity.
  • Further research into epigenetics offers insights into evolved insect resistance to pathogens.
