Physiological Barriers

4.3K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

Overview of the Vascular System

3.1K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Area of Science:

  • Neuroscience
  • Physiology
  • Biochemistry

Background:

  • The blood-brain barrier (BBB) is a critical protective interface in the central nervous system.
  • It regulates the passage of substances between blood and brain tissue, maintaining neural function.
  • BBB integrity is essential for preventing neurotoxicity and supporting brain health.

Purpose of the Study:

  • To review the cellular and molecular components supporting BBB development and function.
  • To elucidate the transport pathways across the BBB.
  • To discuss BBB dysfunction, its neuropathological consequences, and potential biomarkers.

Main Methods:

  • Comprehensive literature search across major scientific databases (Google Scholar, PubMed, Web of Science, Saudi Digital Library).
  • Synthesis of information on BBB structure, function, transport mechanisms, and pathology.
  • Identification and discussion of biomarkers for BBB disturbances.

Main Results:

  • Detailed overview of BBB-supporting cells and molecular components.
  • Explanation of various molecular transport pathways between blood and brain.
  • Identification of key factors contributing to BBB dysfunction and associated neuropathologies.
  • Potential biomarkers for predicting BBB disturbances were identified.

Conclusions:

  • A thorough understanding of the BBB is crucial for advancing neurological research.
  • Biomarkers can aid in predicting and managing BBB-related disorders.
  • Targeted delivery systems and nanotherapy show promise for treating brain pathologies involving BBB modification.
