1. A recently developed method of measuring cytoplasmic Ca2+ buffering in intact red cells was applied to re-evaluate the intracellular Ca2+ binding properties of the Ca2+ chelators benz2 and BAPTA. Incorporation of the free chelators was accomplished by incubating the

Glioblastoma multiforme (GBM) is a highly aggressive type of brain tumor with an extremely poor prognosis. Recent evidences have shown that the "biomechanical imbalances" induced in GBM patient-derived glioblastoma cells (GC) and in vivo via the administration of synthetic small

In an attempt to probe the relationship between excitotoxicity and increases in intracellular calcium ([Ca2+]i), BAPTA-AM and its analogs were applied to cultured hippocampal neurons. Chelation of [Ca2+]i depressed and prolonged transient responses to glutamate and did not effect elevation

Leukocyte extravasation is an essential step during the immune response and requires the destabilization of endothelial junctions. We have shown previously that this process depends in vivo on the dephosphorylation of VE-cadherin-Y731. Here, we reveal the underlying mechanism. Leukocyte-induced stimulation

We have shown that sphingosine 1-phosphate (S1P) generated by sphingosine kinase 2 (SK2) is toxic in neurons lacking S1P-lyase (SGPL1), the enzyme that catalyzes its irreversible cleavage. Interestingly, patients harboring mutations in the gene encoding this enzyme (SGPL1) often present
