Phagocytic cells are studded with plasma membrane proteins known as toll-like receptors (TLRs) that recognize __________typically found on viral and bacterial cell walls.

pathogen-associated molecular patterns (PAMPs)

Macrophages and other phagocytic cells detect pathogens by their _________

Toll like receptors TLR's

Plasma cells swell as they add large amounts of the organelle known as ___________ for protein production

endoplasmic reticulum

Type of leukocytes that respond to antigens only when they are bound to specific molecules called major histocompatability complex (MHC) proteins

T cells

The type of MHC molecules that are found and antigen presenting cells (APCs) such as macrophages and dendritic cells

MHC II

The type of MHC molecules that are found on all nucleated human cells and are the proteins that are the cell’s self-antigens.

MHC I

What type of receptors are found on T cells

TCRs T cell receptors

What type of receptors are found on B cells

BCRs ( B cell receptor)

3 types of T lymphocytes

killer T, helper T, suppressor T

Type of leukocyte that kill virus-infected and cancerous cells. Can differentiate into many other cells (killer T, helper T, suppressor T)

T lymphocytes

professional antigen presenting cells are

macrophages, dendritic cells and B cells

Neutrophils, basophils, and eosinophils are all considered to be _______ that can be found circulating in the bloodstream

PMNs or polymorphonuclear leukocytes

3 actively phagocytic cells are...

dendritic cells, macrophages, neutrophils

Are specialized antigen presenting cells (APCs) that when activated present the antigens to lymphocytes to activate them.

dendritic cells

when activated these cells present the antigens to lymphocytes to activate them. They include macrophages and B cells.

antigen presenting cells (APC'S)

Type of cells that are found in the connective tissue of skin, lungs, and the gastrointestinal tract have a similar function as basophils in that they can release histamine and heparin.

mast cells

derived from monocytes, These cells remain is a particular tissue; Example: alveolar macrophages, kupffer cells in liver, microglia

fixed monocytes

derived from monocytes and roam tissues and gather at sites of infection and inflammation.

wandering macrophages

Type of leukocytes that migrate from blood into tissues where they enlarge and become macrophages that are active phagocytes.

monocytes

General term for the type of leukocytes responsible for cell-mediated immunity.

T lymphocytes

Type of leukocyte that kill virus-infected and cancerous cells.

Cytotoxic T lymphocytes

Type of leukocyte responsible for antibody-mediated or humoral immunity

B lymphocyte

Type of leukocyte that differentiates into plasma cells and secrete antibodies (immunoglobulins)

B lymphocyte

Type of agranular leukocyte with dark U or kidney-shaped nucleus

monocyte

The fourth most common type of leukocyte in a normal blood sample.

eosinophil

The third most common type of leukocyte in a normal blood sample.

monocyte

The second most common type of leukocyte in a normal blood sample.

lymphocyte

Type of leukocyte that circulate in the blood and have granules that contain histamine - a vasodilator and heparin - an anticoagulant

basophil

Type of leukocyte that help reduce the severity of allergy attacks by phagocytosing the immune complexes; kill parasites such as flatworms

eosinophils

Type leukocyte that increase in number during an allergy attack

eosinophils

The type of large bone marrow cell that forms platelets

megakaryocytes

Immature neutrophils are sometimes called

bands

Type of leukocytes that can increase in number during an acute bacterial infection. These dead cells along with cell debris, and fluid can accumulate as pus at sites of infections

neutrophils

___ or PMNs, are a special family of white blood cells that includes immune cells known as neutrophils, eosinophils, and basophils.

polymorphonuclear leukocytes

Leukocytes are formed in the _______ by a process of leukopoiesis

red bone marrow

General term for the type of cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
