Cytokines are an important factor in which process regarding T cells?
Antibody-mediated immunity depends on the antibody receptors that are expressed on this type of cell.
MHC stands for:
Dendritic cells, macrophages and activated B cells are examples of what?
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
Do antibodies recognize epitopes?
A T cell receptor binds to and recognizes self-peptides. Is the fate of this cell death or survival?
What type of MHC protein is found on an APC?
You want a T/B cell to be self-tolerant and immunocompetent. This is the result of what process?
This type of immunity defends the body against pathogens inside cells (i.e. viruses).
This type of cell engulfs antigens, breaks it up into fragments, and displays a piece on its surface to be recognized by T cells.
APC stands for:
Which lymphocyte has high specificity?
Antigenic determinants are present on antigen cell surfaces. This is what T/B cells recognize. What is another name for them?
True or false: antibody-mediated immunity defends the body against antigens and pathogens in the cytoplasm.
A pathogen visits you again. Your immune response is faster and more intense because of which property of the immune response?
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?
True or false: T/B cells become immunocompetent before they encounter antigens.
Killer T cells bind to any cell with an MHC I on its surface. Which type of CD protein does it utilize?
A cell is infected by an intracellular antigen. Can this cell present a fragment of the antigen on its surface?
MHC I proteins are found only on what type of cell?
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
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.
An immature does not recognize self-MHC molecules. Is this an issue?
T cell activation requires costilmulation. Without this, the cell would become tolerant of what?
Which lymphocyte has broad specificity?
True or false: negative lymphocyte selection keeps T cells that are strongly anti-self.
Phagocytic mobilization has four steps. Leukocytosis, Margination, ???, and Chemotaxis.
An APC is technically not 'infected' by an antigen. What process must take place in order to an APC to possess an antigen?
True or false: antibodies or T cell receptors recognize multiple antigens in order to allow for a wider range of responses.
CD stands for:
Helper T cells only bind to MHC II cells and therefore have which type of CD protein?
Cell-mediated immunity depends on the receptors on which cells?
