Which of the following is a protein involved with the innate immune response? eosinophil Immunoglobulin M fibrin lysozyme

Which of the following steps are part of the processing of antigen by immune cells? Select all that apply.   The vesicle containing the antigen fuses with a lysosome.   Enzymes in the lysosome digest the antigen into components that bind to MHC markers.   The antigen is initially released from the phagocytic cell via exocytosis.   The antigen-MHC complex becomes displayed on the cell's interior.

Some strains of the human papilloma virus (HPV) are resistant to interferons. If HPV can inhibit interferon binding to cells, what advantage does this give the virus?   Question 2 options:   Antiviral proteins will not be synthesized in neighbouring cells.   Interferons will be released by non-infected neighbouring cells.   Interferons will bind to the virus to neurtralize it.   Interferons tell the virus-infected cells to apoptose.   The viruses will be warned that a host is coming.

immunity is characterized by the activation of T-cells that can attack and destroy the invaders hypersenitivity innate cell-mediated humoral

Macrophages typically present antigens to T cells. However, macrophages that reside in the subcapsular sinus are able to present antigens to B cells. What enables them to do this? endocytosis CR1 and CR2 expression phagocytosis ingestion and degradation of the antigens OOOO

Explain the process of phagocytosis, including the steps involved, using a series of labelled drawings drawn by you. Give reasons to explain why phagocytosis is an important and effective defence mechanism of destroying pathogens during body’s innate immune responses. Explain phagocytosis as a defence mechanism with references in Harvard style

Which of the following is a result of activation of the compliment? triggered inflammation all can occur after activation of compliment increased cytolysis increased phagocytosis

Some immune system cells like B lymphocytes and T lymphocytes must first be "trained" in either the bone marrow or thymus because they can do their jobs. Which of the following best describes the purpose of this "training" during their maturation?   to selectively remove any lymphocytes that show immunity against our own cells and our own antigens in our body   to expose these cells to all of the potential pathogens and their antigens they may encounter in the future   to activate them so that they differentiate into plasma and memory cells and begin producing antibodies   to make sure that each lymphocyte is capable of recognizing a large number of different pathogen antigens   to initiate a secondary and stronger immune response after encountering an invading pathogen

What type(s) of biological molecule(s) are the best at inducing immune responses? What properties make these molecules good antigens? (Remember: the biological molecules are lipids, carbohydrates, proteins, and nucleic acids)

Multiple Sclerosis is a disorder in which there is autoimmune-activity to myelin in the central nervous system.  This means increased immune reactivity to Multiple Sclerosis is a disorder in which there is autoimmune-activity to myelin in the central nervous system.  This means increased immune reactivity to -oligodendrocytes -Schwann cells -microglia -astrocytes
