Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

2.0K
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...

Organization of the Nervous System

12.7K
The nervous system is one of the most complex systems in our body. It is organized into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS, comprising the brain and spinal cord, houses billions of neurons. The brain is housed in the skull, while the spinal cord is linked to the brain through the foramen magnum of the occipital bone and is surrounded by the protective structure of the vertebral column. It is responsible for processing various...

Neurotransmitters

3.7K
Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

Neurotransmitters

9.8K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

The World Health Organization (WHO) is a specialized agency of the United Nations based in Geneva. The WHO has many initiatives that center around health. Primarily, they lead global efforts to expand universal health coverage using science-based policies and programs. They are also responsible for shaping health research agendas and developing norms and standards.
The WHO provides expert team support, including funding, vaccines, testing, and treatment tools at the country level to fight...

Area of Science:

  • Infectious Diseases
  • Neuroscience
  • Public Health

Background:

  • Central nervous system opportunistic infections are prevalent in human immunodeficiency virus (HIV)-positive populations globally.
  • Resource-limited settings face significant challenges in diagnosing and treating these infections.

Purpose of the Study:

  • To review recent studies on the pathogenesis, diagnosis, and treatment of cryptococcal meningitis, tuberculous meningitis, and progressive multifocal leukoencephalopathy in HIV-positive individuals in resource-limited settings.

Main Methods:

  • Review of recent scientific literature focusing on central nervous system opportunistic infections in HIV-positive patients.
  • Analysis of studies addressing diagnostic tools, therapeutic strategies, and antiretroviral therapy (ART) timing.

Main Results:

  • Urgent need for rapid point-of-care diagnostics for cryptococcal and tuberculous meningitis in low-income settings.
  • Amphotericin plus flucytosine showed reduced mortality in cryptococcal meningitis; high-dose rifampicin and moxifloxacin improved outcomes in tuberculous meningitis.
  • Deferred ART initiation was associated with better survival in cryptococcal meningitis; predictors of immune reconstitution inflammatory syndrome require further validation.

Conclusions:

  • Recent research offers promising findings for the diagnosis and treatment of central nervous system opportunistic infections in HIV-positive populations.
  • Increased funding and research commitment are crucial to sustain progress and improve global outcomes.
