Q&As (5)

Ask a question
How does CAR-T cell therapy work to combat CD19-expressing cancers? 02/11/2023

CAR-T cells are engineered to express a receptor that recognizes CD19 on the surface of cancerous B cells. When they encounter these cells, they destroy them.

Are there any diseases associated with CD19 dysfunction? 12/07/2022

CD19 deficiencies can lead to primary immunodeficiencies, making individuals more susceptible to infections.

What are the potential side effects of CAR-T cell therapy targeting CD19? 01/26/2022

Side effects may include cytokine release syndrome (CRS), neurologic toxicity, and long-term B-cell aplasia.

What are some CD19-expressing malignancies that CAR-T cell therapy can target? 07/17/2021

CAR-T cell therapy is used to treat B-cell malignancies such as acute lymphoblastic leukemia (ALL) and certain types of non-Hodgkin lymphoma.

How effective is CAR-T cell therapy in treating CD19-expressing cancers? 08/26/2019

CAR-T cell therapy has shown remarkable effectiveness in inducing remissions in patients with CD19-positive malignancies, particularly in those who have relapsed or failed conventional treatments.
