What is B cell therapy?
B-cell therapy (also called B-cell depletion therapy) is a treatment for people with multiple sclerosis (MS). It targets cells called B cells that damage nerves in your brain and spinal cord. B-cell therapy isn’t a cure, but it can: Ease symptoms. Help prevent relapses.
Is rituximab B cell therapy?
Rituximab is a human/murine chimeric anti-CD20 monoclonal antibody. It is largely used to treat B cell malignancies and has become standard in the management of B cell‑mediated diseases such as rheumatoid arthritis and granulomatosis with polyangitis.
Which drugs are B cell depleting?
Table 1
| Agent | Type of Therapy | B-cell Lineages Affected |
|---|---|---|
| Rituximab | Anti-CD20 | From pre-B cells to memory cells |
| Ocrelizumab | Anti-CD20 | From pre-B cells to memory cells |
| Ofatumumab | Anti-CD20 | From pre-B cells to memory cells |
| Epratuzumab | Anti-CD22 | Mature CD27 cells |
What happens when you deplete your B cells?
In the 10 years or so since the widespread use of B-cell depletion, there is little to suggest that a long-term paucity of B cells puts patients at risk for malignancy or opportunistic infections, nor that it leads to treatment-resistant RA or complications.
How long does it take to replenish B cells?
Circulating B cells are replenished from bone marrow pro-B cells within 4 to 12 months after depletion, sometimes longer.
What are B-cell diseases?
B cells serve as APCs in autoimmune diseases including rheumatoid arthritis and type 1 diabetes [61, 62]. Immunoglobulin-deficient mice in a model of autoimmune arthritis (proteoglycan-induced arthritis) did not develop arthritis.
How long does it take for B cells to heal after Rituxan?
Treatment with rituximab results in complete B cell-depletion within 72 h. Recovery of B cell counts usually starts only 6-9 months after the completion of therapy, and normal levels are obtained after 9-12 months (5).
How long can you stay on Rituxan?
Rituxan can provide up to 6 months of symptom improvement from 1 course of treatment (2 infusions given 2 weeks apart). Be sure to talk with your doctor to find out if starting and continuing treatment with Rituxan is right for you.
How do you keep B cells healthy?
These strategies might include:
- eating a diet rich in fruits and vegetables.
- exercising regularly.
- maintaining a healthy weight.
- quitting smoking.
- drinking alcohol only in moderation.
- getting enough sleep.
- avoiding infection through regular hand washing.
- reducing stress.

Do B cells fight viruses?
B-cells are the type of cells that produce antibodies to fight bacteria and viruses. These antibodies are Y-shaped proteins that are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells.
How can I get healthy B cells?
Healthy ways to strengthen your immune system
- Don’t smoke.
- Eat a diet high in fruits and vegetables.
- Exercise regularly.
- Maintain a healthy weight.
- If you drink alcohol, drink only in moderation.
- Get adequate sleep.
- Take steps to avoid infection, such as washing your hands frequently and cooking meats thoroughly.
What is the most severe B cell deficiency?
Affected patients often present early in life with failure to thrive and disseminated infection. DiGeorge syndrome is one of the most recognized disorders in this category, and severe combined immunodeficiency is the most severe.
Do you lose hair with Rituxan?
Hair loss. Hair loss is a possible side effect of Rituxan. However, in clinical trials, hair loss occurred only in people who took Rituxan for pemphigus vulgaris (PV). PV is a condition in which your skin and mucous membranes develop serious and painful blisters.
How can I increase my B-cells naturally?
What vitamins are good for B-cells?
Vitamin A and RA regulate the maturation and differentiation of B cells at multiple levels that, in combination, regulate and often potentiate antibody production overall.
