They do not produce antibodiesuntil they become fully activated. Each B cell has a unique receptor protein (referred to as the B cell receptor (BCR)) on its surface that will bind to one particular antigen. If the pathogens are

Agammaglobulinemia 1. What are the differences between non-specific and specific (immunity) body defense? Non-specific defenses attack any foreign invaders by physical and chemical barriers first and then internally. Specific defenses are our immune system and the immune response that forgets specific invaders of the body that manage to get by the non-specific defenses. 2. In what tissue do B- and T- lymphocytes originate and what are the two steps involved in lymphocyte “maturation”? The precursors

extreme immune system response to an infection that has spread throughout the blood and tissues. Severe septic shock often causes extremely low blood pressure‚ which limits blood flow to the body and can result in organ failure and death.

According to an article written by Dr. Sarah Myhill‚ “immunizations can erode the immune system‚ cause cancers‚ are related to development of autism in children‚ and cause flares of chronic fatigue syndrome” (Myhill). Vaccines cause immune suppression and can permanently damage the immune system‚ making individuals more susceptible to viruses and possibly lymphatic cancers (ProCon.org). Other conditions associated with vaccines such as
