Expanding SPG18 clinical spectrum: autosomal dominant mutation causes complicated hereditary spastic paraplegia in a large family.

Background: SPG18 is caused by mutations in the endoplasmic reticulum lipid raft associated 2 (ERLIN2) gene. Autosomal recessive (AR) mutations are usually associated with complicated hereditary spastic paraplegia (HSP), while autosomal dominant (AD) mutations use to cause pure SPG18.

Aim: To define the variegate clinical spectrum of the SPG18 and to evaluate a dominant negative effect of erlin2 (encoded by ERLIN2) on oligomerization as causing differences between AR and AD phenotypes.

Chronic exposure to l-BMAA cyanotoxin induces cytoplasmic TDP-43 accumulation and glial activation, reproducing an amyotrophic lateral sclerosis-like phenotype in mice.

Background: Amyotrophic lateral sclerosis (ALS) is a progressive and often fatal neurodegenerative disease characterized by the loss of Motor Neurons (MNs) in spinal cord, motor cortex and brainstem. Despite significant efforts in the field, the exact pathogenetic mechanisms underlying both familial and sporadic forms of ALS have not been fully elucidated, and the therapeutic possibilities are still very limited. Here we investigate the molecular mechanisms of neurodegeneration induced by chronic exposure to the environmental cyanotoxin L-BMAA, which causes a form of ALS/Parkinson's disease (PD) in several populations consuming food and/or water containing high amounts of this compound.

HIPK2 in the physiology of nervous system and its implications in neurological disorders.

HIPK2 is an evolutionary conserved serine/threonine kinase with multifunctional roles in stress response, embryonic development and pathological conditions, such as cancer and fibrosis. The heterogeneity of its interactors and targets makes HIPK2 activity strongly dependent on the cellular context, and allows it to modulate multiple signaling pathways, ultimately regulating cell fate and proliferation. HIPK2 is highly expressed in the central and peripheral nervous systems, and its genetic ablation causes neurological defects in mice.

Phloroglucinol-Derived Medications are Effective in Reducing Pain and Spasms of Urinary and Biliary Tracts: Results of Phase 3 Multicentre, Open-Label, Randomized, Comparative Studies of Clinical Effectiveness and Safety.

Introduction: Pain and spasms of urinary and biliary tracts are conditions causing poor quality of life. Treatment with analgesic drugs such as non-steroidal anti-inflammatory drugs and modulators of the parasympathetic system are not always tolerated, and often additional therapeutic options are necessary. The present analysis aimed to evaluate the pharmacokinetics and effectiveness of oral and parenteral preparations based on phloroglucinol in reducing pain and spasms associated with renal or biliary colic in phase 3, multicentre, open-label, randomized, comparative studies on clinical effectiveness and safety.
