Ocrevus' mechanism of action Ocrelizumab selectively targets the CD20-positive B-cells by binding to the surface proteins of the cells and protecting the nerve cells from mediated damage caused by CD20-positive B lymphoma cell lines.
How much does Ocrevus suppress immune system?

Does Ocrevus target all B cells?
“Our results demonstrate that treatment with [Ocrevus] does not exclusively target B-cells, but also CD20+ T-cellsT-cellsT-cell growth factors acronym: TCGF(s) are signaling molecules collectively called growth factors which stimulate the production and development of T-cells. A number of them have been discovered, among them many members of the interleukin family. The thymus is one organ which releases TCGFs.https://en.wikipedia.org › wiki › T-cell_growth_factorT-cell growth factor - Wikipedia, which account for a substantial amount of CD20-expressing cells,” the researchers wrote.Jan 15, 2019
