|
first 30 days posttransplant
Cautions 1. prolonged neutropenia 2. breaks in the mucocutaneous barrier |
|

|
Impaired cell-mediated immunity
key factors: extent of GVHD and level of immunosuppressive |
|
CMV
|
causes pneumonia, hepatitis, and colitisis and potentiates superinfection with opportunistic pathogens
|
|
Antigen Presenting Cells
|
is a cell that displays foreign antigen complex with MHC on its surface
|
|
Antibodies
|
circulate in the blood and bind to antigens on infectious agents
- inactivation of microorganism - activation of inflammatory response |
|
Humoral immunity
|
is the aspect of immunity that is mediated by secreted antibodies (B Cells)
|
|
T Cells become
|
T regulatory cells
Cytotoxic T Cells Memory T Cells |
|
Cytotoxic T cells
|
directly attack and kill targets directly
Cellular immunity |
|
Passive Acquired Immunity
|
does not involve the host's immune response but rather occurs when preformed anitbodies or T lymphocytes are transferred from a donor to the recipient.
For example, IVIG administration |
|
CD
|
Cluster of differentiation
large family of protiens found on the surface of cells |
|
antigens is immunogenic based on
|
- foriengnness to the host
- appropriateness in size - having an adequate chemical complexity - being present in a suggicient quantity |
|
MHC
|
major histocompatibility complex
recognition molecules antigen presention is the primary role of molecules of the MHC - glyco protien found on the surface of all human cells except RBC Class I or II |
|
Humans have two copies of each MHC locus (one inherited from each parent) that are co-dominant so that molecules encoded by each parent's genes are expressed on the cell surfae.
|
Within an individual, each locus will be expressing only one allele. For example, each person will have only two different A protiens ( one from each parent). However, with the tremendous number of possible alleles that can be expressed, it is likely that any two unrelated individuals will have different sets of MHC molecules on their cell surface.
|
|
Rejection happens when
|
a different set of MHC surface antigens than those of the recipient are seen as foreign.
|
|
Six major HLA locations
|
A, B, C, DR, DQ, and DP is termed a haplotype
|
|
Haplotype
|
Each individual has two haplotypes: one from teh paternal chromosome 6 and another from the mother
|
|
Antigen presenting molecules
|
Class I MHC
Class II MHC CD 1 |
|
CD1 molecules specialize in
|
lipid antigens contained in lipoprotiens, glycoplipids, and other molecules. Usuaully bacterial with the Mycobacterium spp.
(e.g. Mycobacterium tuberculosis) |
|
anitbody
|
immunoglobin
produced by plasma cells (B) |
|
5 types of immunoglobins
|
IgG
IgA IgM IgE IgD |
|
IgG
|
most common
protect against infection IG 1-4 |
|
IgA
|
IgA 1-2
A1 in the blood A2 normal body secretions mucosal epothelial cells that protect against degradation by enzymes It is found in body secretions such as saliva, sweat, or tears. IgA prevents the attachment of viruses and bacteria to skin and intestinal lining surfaces. |
|
IgM
|
initial/primary response to antigen
early on in an infection |
|
IgD
|
on immature and developing B lymphocytes
low amounts in serum |
|
IgE
|
least concentrated
allergic responses defends against parasites |
|
cytokines
|
chemical signals between cells
i.e IL 1 start + or - regulation responses fx: target cells (1)to proliferate and differentiate, (2) create proteins can effect not only lymphocytes but inflammatory responses and hematopoietic cells can be antagonistc - inducing opposite effects on the cell |
|
IL1
|
T cell to prolifteration and di fferentiation; induces acute phase proteins in inflammatory response; endogenous pyrogens
|
|
neutrophils
|
phagocytes
early inflammatory process short lived component of the purulent exudate - pus |
|
monocytes or macrophages
|
same as neutrophils but for a longer time and in a later stage of the inflammatory process
activate the adaptive immune system |
