Myasthenia gravis is an autoimmune neuromuscular disease characterized by weakness of the skeletal muscles due to antiacetylcholine receptor antibodies; thymectomy is a successful treatment for this condition in some patients because it:
a. removes all auto-reactive B cells from the body
b. primes APC to reverse their response to self tissue
c. neutralizes the autoantibodies from the body
d. produces proteins to bind the autoantibodies before reaching their target
e. prevents further miseducation of T-cell population
Answer: prevents further miseducation of T-cell population

- A Herpesviridae viral infection would most likely stimulate which immune cells for clearance of the infection?
- Anti-Streptococcus antibodies found in the serum of a patient during a primary antibody response differ from the antibodies produced during a secondary response to the same antigen because of:
- During the course of an intestinal infection with Salmonella enteritidis, the B cells undergo class switching; what switching is most likely to occur and what causes the switch?
- RAG1 and RAG2 are enzymes that control gene splicing on B-cell antibody genes, which order are segments worked on in the creation of the heavy-chain gene segment?
- Genes for the heavy-chain-antibody production consist of __________ segments, whereas genes for the light-chain-antibody production consist of __________ segments.
- An example of an antigen that could stimulate naïve B-cell proliferation and differentiation without the help of a T cell would be:
- Capping of B-cell receptors on the surface of an antigen-exposed B cell immediately causes what to occur?

I was diagnosed with Myasthenia Gravis in 2014, 2 years after they removed a tumor on my thymus. It's been an okay road. Had one flare which put me in the hospital 4 years ago and this previous year I have been in and out of the hospital trying to see which treatment can get me back feeling 100% again. Pyridostigmine bromide just makes me nauseous all day and didn't help my droopy eye or swallowing so I need to try something else which was natural herbs recommendation from multivitamincare. org This herbal treatment has successfully cure my MG and am 100% free ,I completed the herbal treatment program last year December and am very delighted i came across their website.it starts in the eyes and face then bulgar muscles , without treatment or the proper dosages of treatment it goes on to my limbs and then neck and breathing muscles but I can happily say that am free from MG after taking my chances to try natural herbs ,my neurologist was surprise after my result of being totally cured with herbal cure from the org.
