BB H 432 Lecture Notes - Lecture 12: Immunocompetence, Nasal Spray, Cortisol
Document Summary
The non specific response: inflammation is one of the first responses, redness, swelling, heat and pain, during the acute phase of inflammation, site of inflammation in a process called neutrophils chemotaxis. migrate toward the. V: called into action when nonspecific methods are not enough and infection becomes widespread. B cells: specific targets: humoral immunity (antibody-mediated immune system) : secretes antibodies that coat and neutralize infected cells, helps other cells identify and kill infected cells, facilitates nk and t cell killing. Viii. lifetime: upon second exposure, the small number of memory cells divide and create many, many plasma cells to pump out antibodies. Cortisol effect on immune cells (look at slide!) It is considered health to have a robust proliferative response. Glaser r et al (2000) chronic stress modulates the immune response to a. Cohen, doyle, and skoner, 1999: 55 students: completed perceived stress scale, split into high vs low stress groups, students quarantined, exposed to influenza virus by nasal spray.
