FALSE. A granuloma is a focal area of walled–off chronic infection made of macrophages, lymphocytes and plasma cells
Leukocyte: ANY WBC Lymphocyte: only T cells, B cells, and NK cells.
Foreign body type (response to inert foreign bodies); Immune type (usually microbial, esp. tuberculosis)
Lymphangitis is an infection of the lymph vessels
Lymphadenitis is an infection of the lymph nodes
Blood stream infection
class of proteins whose plasma concentrations increase (positive acute–phase proteins) or decrease (negative acute–phase proteins) in response to inflammation. This response is called the acute–phase reaction (also called acute–phase response). Mostly liver derived. Act as opsonins and fixing complement
WBC count rise 15–20k; seen with bacterial infections
Healing by scar, NOT regeneration, occurs
T
Summoning resting or quiescent cells into the cell cycle (less important is shortening the cell cycle)
Stable cells are usually in G0 but can be driven into G1 and rapid proliferation (eg., liver, kidney, pancreas, fibroblasts). Labile cells are always dividing to replace dying cells.
