During infection with Listeria, an intracellular bacterium, APCs will present antigen on MHC II molecules and triggers a phagocytic property by stimulating the release of macrophages.
What is the role of macrophages in Phagosomes?
Phagosome maturation was formerly regarded to be a very simple notion that described how much phagosomes had united with lysosomes.
- Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.
- Proteins, such as the NADPH oxidase complex that creates the superoxide burst, may be seen being assembled on the phagocytic cup even before they are fully formed.
- When the phagosome closes and the maturation process begins, it becomes increasingly acidic and hydrolytically active, and it transiently fuses with the recycling endosomal system, the secretory system, including secretory lysosomes, multi-vesicular bodies such as the MHC class II (MIIC) compartment, and even the endoplasmic reticulum.

Answer:
Coombs reagent is an antiserum with antibodies that bind to the human <u>antibodies attached on the surface of the erythrocytes.</u>
Explanation:
Coombs test is a blood test used in immunology and immunohematology. It is of two types: direct and indirect.
The Coombs reagent is an antiserum, containing antibodies.
The direct Coombs test detects the antibodies present on the surface of the erythrocytes.
In this test, when the Coombs reagent is reacted with the blood to be tested, <u>the antibodies in the Coombs reagent binds to the antibodies attached on the surface of the erythrocytes in the test blood and cause agglutination.</u>
it is a stationary front because the stationary fron does not move from one place.
