Ocrelizumab is a recombinant humanized monoclonal antibody selectively targeting CD20-expressing B cells. The effect of ocrelizumab on primary progressive multiple sclerosis (PPMS) has been evaluated during phase 3 trials that enrolled patients under 55 years with a maximum Expanded Disability Status Scale (EDSS) of 6.5.

Methods: In this study we evaluated GRN genetic variability in 400 MS patients, in correlation with clinical variables such as disease severity and relapse recovery.
Background: Progranulin (PGRN) is a fundamental neurotrophic factor, and is also involved in inflammation and wound repair. PGRN may have pro- or anti-inflammatory properties, depending upon proteolysis of the anti-inflammatory parent PGRN protein and the generation of pro-inflammatory granulin peptides.
Objectives: Our objectives were as follows: (1) to evaluate the presence and distribution of PGRN in multiple sclerosis (MS) brain tissue, correlating it with demyelination and inflammation; (2) to evaluate cerebrospinal fluid (CSF) PGRN concentrations in patients with MS and controls, in relationship to the clinical features of the disease.
