The blood-brain barrier (BBB) is a one-cell layer barrier that separates the brain from the blood. Its main role is to act as a selective (semi-permeable) filter that lets only specific molecules through while blocking others at the right time. The brain becomes “leaky” when the blood-...
The blood-retinal barrier is part of the blood-brain barrier, which is generally reported to be impermeable to most molecules (Paulson, 2002; Wong et al., 2013). Here we assume a good approximation for the blood-retinal barrier is the blood-brain barrier, so we look to the blood-brain ...
The intricacies of tick-borne flavivirus (TBEV, POWV) development, resolution, and associated neuropathology, despite recent investigations into viral-host interactions within encephalitic disease, continue to be enigmatic. T cells, having navigated the selectively permeable blood-brain barrier, have emer...

These compounds demonstrated favorable intestinal and oral absorption, bioavailability, blood-brain barrier penetration, low skin permeability, and no inhibition of cytochrome P450 enzymes. PacBio and ONT Binding to the BACE1 receptor by forty-four ligand molecules resulted in docking scores varying from...
inbloodsupply to that part of the brain. But in Alzheimer's disease the blood supply is often impaired, so the amount of energy supplied to the brain cells is compromised. One of the reasons for the breakdown in this energy supply may be explained by a breakdown in theblood-brain barrier...
Escherichia coli is the leading cause of neonatal Gram-negative bacterial meningitis, but the pathogenesis of E. coli meningitis remains elusive. E. coli penetration of the blood–brain barrier (BBB) is the critical step for development of meningitis. He
The integrity of myelinated axons relies on homeostatic support from oligodendrocytes (OLs). To determine how OLs detect axonal spiking and how rapid axon–OL metabolic coupling is regulated in the white matter, we studied activity-dependent calcium (Ca2

“needle”. An increase of internal pressure causes the filament to extrude and the sporoplasm is then expelled via the filament lumen, allowing it to penetrate the gut epithelium and travel to tissues elsewhere in the body via the blood stream (Noble et al., 1989; Percy and Barthold, ...
