L2-immunology Flashcards
Which immune cells signal acute inflammation?
NeutroPhils (QUICKLY NEUTROLIZE THE THREAT!)
Which immune cells signal chronic inflammation?
Macrophages(monocytes) (slow to get to the party)
What are the three main bacteria involved in bacterial meningitis?
1.Streptoccus Pneumoniae 2. Haemophilus Influenza 3.Neisseria Meningitis
What are the three main features of the innate immune system?
1.broad 2.fast 3. no memory
What are the three main features of the adaptive immune system?
1.specific 2.slow 3.memory
What are the 3 types of endotoxin?
1.Super Antigen 2.Cytolytic 3.A-B Toxin
Which antibodies can cross the placenta?
IgE
What is the most antibody made?
IgA
What are the response molecules in the first part of inflammation? What are the ‘sentinel’ cells that release them?
Histamine released from mast cells
What type of cell is going to show the CAM ‘stop signs’?
endothelial cells are going to display the Cell Adhesion Miolecules
What are the receptors present on phagocytes that allow them to grab on to the opsonizied pathogen?
Fc receptors
What type of cell releases cytokines?
T-cells (T helper cells)
What is the first cell in action to recognize S. Pneumonia?
B-cells, they then tell T cells to clone and release cytokines, as well as tell B cells to make antibodies toward that pathogen
What antibody is associated with Type I hypersensitivity?
IgE
Which antibodies are associated with Type II hypersensitivity?
IgG, IgM
