Joana Carvalho, PhD, science editor —

Joana holds a bachelor’s in biology, a Master of Science in evolutionary and developmental biology, and a PhD in biomedical sciences from Universidade de Lisboa, Portugal. Her work has been focused on the impact of non-canonical Wnt signaling in the collective behavior of endothelial cells — those that make up the lining of blood vessels — found in the umbilical cord of newborns. In addition to several research fellowships, she was awarded two Erasmus scholarships to conduct part of her studies in France.

New Zealand Expands Patient Access to Funded MS Treatments

New Zealand will expand patient access to a list of funded treatments for multiple sclerosis (MS), starting on March 1. The government health agency, PHARMAC, will extend eligibility criteria to include MS patients with expanded disability status scale (EDSS) scores ranging from zero to six. EDSS is a validated…

Newly ID’d Group of Astrocytes Seen to Help Prevent Brain Inflammation

A newly identified subset of astrocytes — cells long thought to be responsible for simply providing nutrition and support to neurons — can prevent brain inflammation by promoting the destruction of pro-inflammatory immune T-cells, scientists report. Their work also found that the anti-inflammatory activity of this astrocyte subpopulation is dependent on…

GW Pharma Plans More Clinical Trials for Sativex

GW Pharmaceuticals is planning to continue recruiting patients into two pivotal Phase 3 clinical trials of Sativex (nabiximols), an oral spray that contains cannabis extracts and is being investigated as a potential add-on therapy for people with multiple sclerosis (MS) and spasticity. The company also is…

Plegridy as Intramuscular Injection for RRMS Approved in Europe

The European Commission (EC) has approved a new, intramuscular formulation of Plegridy (peginterferon beta-1a) to treat people with relapsing-remitting multiple sclerosis (RRMS). This new mode of administration — in which Plegridy is directly injected into the muscle, rather than under the skin (subcutaneously) — does…

Scientists Create Oligodendrocytes From Stem Cells in Lab Dish in Just Three Weeks

Scientists have created myelin-producing cells, called oligodendrocytes, from pluripotent stem cells derived from patients with multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) in just three weeks. They also demonstrated these lab-made oligodendrocytes were able to produce myelin — the fatty substance that normally wraps around neurons’…

Immune Treg Cells Seen to Ease Paralysis in Mouse Model of MS

Regulatory T-cells (Tregs) — immune cells that normally dampen immune and inflammatory responses by inhibiting the activity of pro-inflammatory immune cells — enabled mice in a model of multiple sclerosis to partly recover from limb and tail paralysis, scientists reported. Tregs can do this by preventing a subtype of…
