; ; ; Benito Vicente, Asier; ; ; ; Martín Plágaro, César Augusto (MDPI, 2021-12-18)
Background: Gain of function (GOF) mutations of PCSK9 cause autosomal dominant familial hypercholesterolemia as they reduce the abundance of LDL receptor (LDLR) more efficiently than wild-type PCSK9. In contrast, PCSK9 ... -
Aberrant Synaptic PTEN in Symptomatic Alzheimer's Patients May Link Synaptic Depression to Network Failure
(Frontiers Media, 2021-05-11)In Alzheimer's disease (AD), Amyloid beta (A beta) impairs synaptic function by inhibiting long-term potentiation (LTP), and by facilitating long-term depression (LTD). There is now evidence from AD models that A beta ... -
