Summary Introduction
To determine:
Whether removal of the thymus is a therapeutic treatment when an individual is suffering from myasthenia gravis
Concept introduction:
Myasthenia gravis is a neuromuscular disorder which leads to weakness in skeletal muscle. It commonly affects the muscles of eyes, face, and so on. This disorder occurs in a body when signals transmitted from nerve to muscle fiber are disrupted.

Be thorough as possible.arrow_forwardStrep throat is commonly caused by group A Streptococcus bacteria. A common symptom of strep throat is the presence of swollen lymph nodes in the neck. This symptom usually peaks about 2–4 days after the onset of the infection, and is due to: Damage to the pharyngeal epithelium by the bacteria Release of bacterial PAMPs leading to inflammatory cytokine production Trapping and activation of antigen-specific lymphocytes in the lymph nodes of the neck Recruitment of neutrophils to the lymph nodes of the neck Recruitment of circulating macrophages to the lymph nodes of the neckarrow_forward

But for some pathogens, such as Streptococcus pneumoniae opsonization by antibodies that bind the thick polysaccharide "capsule" layer surrounding the bacteria is the major mechanism of clearing the infection. As expected, a pure polysaccharide vaccine is not terribly effective, but much better immunity is achieved by vaccinating with a polysaccharide covalently linked "conjugated" to an unrelated protein. Explain how this conjugate vaccine allows B cells capable of making anti-polysaccharide antibodies.arrow_forward
