New Paradigm in Cell Therapy Using Sperm Head to Restore Brain Function and Structure in Animal Model of Alzheimer’s Disease: Support for Boosting Constructive Inflammation vs. Anti-Inflammatory Approach

open access: yesJournal of Immunology Research, 2022
Alzheimer’s is characterized by accumulation of amyloid-β (Aβ) associated with insufficient clearance of toxicants from the brain establishing a chronic inflammation and other abnormalities in the brain.

CLEC-2 and Syk in the megakaryocytic/platelet lineage are essential for development [PDF]

open access: yes, 2011
The C-type lectin receptor CLEC-2 signals through a pathway that is critically dependent on the tyrosine kinase Syk. We show that homozygous loss of either protein results in defects in brain vascular and lymphatic development, lung inflation and ...

New experimental model of acute aqueductal blockage in cats: effects on cerebrospinal fluid pressure and the size of brain ventricles [PDF]

open access: yes, 2009
It is generally assumed that cerebrospinal fluid (CSF) is secreted in the brain ventricles, and so after an acute blockage of the aqueduct of Sylvius an increase in the ventricular CSF pressure and dilation of isolated ventricles may be expected. We have

CSF circulation and dispersion yield rapid clearance from intracranial compartments

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
In this paper, we used a computational model to estimate the clearance of a tracer driven by the circulation of cerebrospinal fluid (CSF) produced in the choroid plexus (CP) located within the lateral ventricles.

Antigen-presenting cells and antigen presentation in tertiary lymphoid organs [PDF]

open access: yes, 2016
Tertiary lymphoid organs (TLOs) form in territorialized niches of peripheral tissues characterized by the presence of antigens; however, little is known about mechanism(s) of antigen handling by ectopic lymphoid structures.

Aquaporin-4 Functionality and Virchow-Robin Space Water Dynamics: Physiological Model for Neurovascular Coupling and Glymphatic Flow. [PDF]

open access: yes, 2017
The unique properties of brain capillary endothelium, critical in maintaining the blood-brain barrier (BBB) and restricting water permeability across the BBB, have important consequences on fluid hydrodynamics inside the BBB hereto inadequately ...

Non-invasive MR imaging of human brain lymphatic networks with connections to cervical lymph nodes

open access: yesNature Communications, 2022
Meningeal lymphatic vessels have been described in animal studies, but limited comparable data is available in human studies. Here we show dural lymphatic structures along the dural venous sinuses in dorsal regions and along cranial nerves in the ventral

New Brain Lymphatic Vessels Drain Old Concepts

open access: yesEBioMedicine, 2015
The brain has traditionally been considered an immune privileged organ, in part due to the lack of evidence for lymphatic vasculature (Galea et al., 2007). Two centuries ago, the existence of lymphatic vessels on the surface of the human brain was proposed but it has since been widely dismissed (Lukic et al., 2003).

Lymphatic vessels of the dura mater: A new discovery? [PDF]

open access: yes, 2015
Two recent paper s (Aspelund et al. 2015; Louveau et al. 2015) reported the presence in mice of lymphatics in the cerebra l dura mater , the most external of the meningeal layers covering the brain.

Circadian control of brain glymphatic and lymphatic fluid flow [PDF]

open access: yesNature Communications, 2020
Abstract The glymphatic system is a network of perivascular spaces that promotes movement of cerebrospinal fluid (CSF) into the brain and clearance of metabolic waste. This fluid transport system is supported by the water channel aquaporin-4 (AQP4) localized to vascular endfeet of astrocytes.
