Neurogenesis and Regeneration of Nervous Tissue

1.9K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Inflammatory Response01:28

Inflammatory Response

17.6K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammatory Response I: Vascular and Cellular

17.5K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

8.4K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Receptor interacting serine/threonine kinase 3 (RIPK3) promotes neuroinflammation during West Nile virus infection. This study shows RIPK3 controls viral infection in the central nervous system without causing neuronal death.

Area of Science:

  • Immunology
  • Virology
  • Neuroscience

Background:

  • Receptor interacting serine/threonine kinase 3 (RIPK3) is known to mediate necroptosis, an inflammatory form of cell death.
  • RIPK3 also has roles in inflammation that are independent of necroptosis, but these are not well understood.

Purpose of the Study:

  • To investigate the role of RIPK3 in the central nervous system during West Nile virus infection.
  • To determine if RIPK3 influences neuroinflammation or neuronal death in the context of viral encephalitis.

Main Methods:

  • The study utilized mouse models of West Nile virus infection.
  • Researchers analyzed the impact of RIPK3 on viral load, neuroinflammation markers, and neuronal survival.

Main Results:

  • RIPK3 was found to control West Nile virus infection in the central nervous system.
  • RIPK3 promoted neuroinflammation without contributing to neuronal death during the infection.

Conclusions:

  • RIPK3 plays a critical role in regulating the host immune response to West Nile virus in the brain.
  • RIPK3's function in promoting neuroinflammation, independent of cell death, highlights its complex role in viral pathogenesis.
