From a paper by Oscar Arias-Carrión, 2008 In an embryonic rat brain, GAD67-binding marker tends to concentrate in subventricular zone. An image from Popp et al., 2009. [1] The subventricular zone (SVZ) is a region situated on the outside wall of each lateral ventricle of the vertebrate brain. [2] It is present in both the embryonic and adult ...

In peripheral organs, lymphatic vessels are responsible for conducting lymph between different parts of the body. In general, lymphatic drainage is important for maintaining fluid homeostasis as well as providing a means for immune cells to traffic into draining lymph nodes from other parts of the body, allowing for immune surveillance of bodily tissues.
Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]
In a study published in 2012, [5] a group of researchers from the University of Rochester, headed by Maiken Nedergaard, used in-vivo two-photon imaging of small fluorescent tracers to monitor the flow of subarachnoid CSF into and through the brain parenchyma. The two-photon microscopy allowed the Rochester team to visualize the flux of CSF in ...
The first compartment is the immune-privileged brain and spinal cord parenchyma. This compartment contains multiple immunosuppressive cell surface proteins such as CD200 and CD95L and it allows for the release of anti-inflammatory factors.
The two layers of the dura mater separate at several places, with the meningeal layer projecting deeper into the brain parenchyma forming fibrous septa that compartmentalize the brain tissue. At these sites, the epidural space is wide enough to house the epidural venous sinuses. [2] [4] [5] There are four fibrous septa: [4]
This is critical because the brain lacks a true lymphatic system. In the remainder of the body, small amounts of protein are able to leak from the parenchymal capillaries through the lymphatic system. In the brain, this ends up in the interstitial space. The protein portions are able to leave through the very permeable pia mater and enter the ...
