Which lymphocyte has broad specificity?
Phagocytic mobilization has four steps. Leukocytosis, Margination, ???, and Chemotaxis.
MHC stands for:
APC stands for:
A T cell receptor binds to and recognizes self-peptides. Is the fate of this cell death or survival?
Cell-mediated immunity depends on the receptors on which cells?
Do antibodies recognize epitopes?
True or false: antibody-mediated immunity defends the body against antigens and pathogens in the cytoplasm.
T cell activation requires costilmulation. Without this, the cell would become tolerant of what?
Antigenic determinants are present on antigen cell surfaces. This is what T/B cells recognize. What is another name for them?
Killer T cells bind to any cell with an MHC I on its surface. Which type of CD protein does it utilize?
True or false: T/B cells become immunocompetent before they encounter antigens.
This type of immunity defends the body against pathogens inside cells (i.e. viruses).
Helper T cells only bind to MHC II cells and therefore have which type of CD protein?
Which lymphocyte has high specificity?
An APC is technically not 'infected' by an antigen. What process must take place in order to an APC to possess an antigen?
What type of MHC protein is found on an APC?
A cell is infected by an intracellular antigen. Can this cell present a fragment of the antigen on its surface?
This type of cell engulfs antigens, breaks it up into fragments, and displays a piece on its surface to be recognized by T cells.
Dendritic cells, macrophages and activated B cells are examples of what?
Cytokines are an important factor in which process regarding T cells?
You want a T/B cell to be self-tolerant and immunocompetent. This is the result of what process?
True or false: negative lymphocyte selection keeps T cells that are strongly anti-self.
True or false: the mechanism by which lymphocyte receptors are developed is not random at all, but, instead, consists of a series of very well known rearrangements of certain gene
A pathogen visits you again. Your immune response is faster and more intense because of which property of the immune response?
MHC I proteins are found only on what type of cell?
An immature does not recognize self-MHC molecules. Is this an issue?
When a B cell does not recognize self-MHC molecules, this is called what?
T cells only recognize epitopes in special cases. What must the epitope be bound to?
Antibody-mediated immunity depends on the antibody receptors that are expressed on this type of cell.
CD stands for:
A lymphocyte expresses a bazillion receptors on its surface. It is activated and proliferates. True or false: its daughter cells will have receptors that are completely identical t
True or false: antibodies or T cell receptors recognize multiple antigens in order to allow for a wider range of responses.
True or false: even identical twins express different MHC proteins
The immune response ability to discriminate between self and nonself is called:
A B cell recognizes an antigen. This process proceeds, allowing the cell to be activated, proliferate and differentiate into plasma cell clones.
