Factors Affecting Drug Distribution: Physiological Barriers

839
Drug distribution in the body is intricately regulated by various physiological barriers that control the passage of substances. These include the capillary endothelial barrier, the blood-brain, blood-cerebrospinal fluid, blood-placental, and blood-testis barriers.
The capillary endothelial barrier allows only smaller molecules below 600 Da (Daltons) to pass through. It also restricts drugs like heparin that are bound to blood components, limiting their movement within the bloodstream.

Physiological Barriers

5.4K
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...

Area of Science:

  • Neuroscience
  • Immunology
  • Vascular Biology

Background:

  • Acute ischemic stroke is a leading cause of death and disability.
  • Tissue plasminogen activator (tPA) is a common thrombolytic therapy for stroke.
  • tPA therapy can compromise the blood-brain barrier (BBB), increasing risks.

Purpose of the Study:

  • To investigate the potential of regulatory T cells (Tregs) to protect the BBB.
  • To evaluate Treg therapy's efficacy in conjunction with tPA in stroke models.

Main Methods:

  • Experimental stroke models were induced.
  • Animals received tPA therapy.
  • Exogenous regulatory T cells were administered.
  • Blood-brain barrier integrity was assessed using various biomarkers and imaging techniques.

Main Results:

  • Treatment with regulatory T cells significantly fortified the blood-brain barrier post-tPA therapy.
  • Reduced microvascular leakage and improved BBB structural integrity were observed.
  • Treg administration mitigated tPA-induced BBB damage.

Conclusions:

  • Exogenous regulatory T cells offer a promising neuroprotective strategy.
  • Treg therapy can enhance the safety and efficacy of tPA treatment for acute ischemic stroke.
  • Targeting BBB integrity with Tregs represents a novel therapeutic approach for stroke recovery.
