Abstract. Here we hypothesized that the water-soluble lysosomal enzymes may cross the bloodâbrain-barrier and reach the brain using the mechanism of unspecific fluid-phase endocytosis.n fact, there has been increasing evidence that when high serum levels of lysosomal enzymes are achieved, either by GT or ERT, a small fraction of the enzyme is able to cross the BBB by mechanisms not clearly understood [6] , [7] and [8] . Table 1.
11.1 Blood-brain Barrier Maintains the Constancy of the Brain's Internal Environment. The blood-brain barrier (BBB) protects the neural tissue from variations in blood composition and toxins.Elsewhere in the body the extracellular concentrations of hormones, amino acids and potassium undergo frequent fluctuations, especially after meals, exercise or stressful times.iscovery of blood-brain barrier. The discovery of the BBB dates back more than 100 years when, in the 1880s, Paul Ehrlich observed that intravenous administration of certain dyes (e.g. trypan blue) stained all organs except the brain and the spinal cord.
