AB Recent studies have identified genes involved in resistance to
intracellular pathogens. Such genes include the murine MHC class I gene,
Ld (toxoplasmosis), HLA-BW53, HLA DRB1* 1302-DQ B10s01 and TNF2
(malaria), murine Nramp (toxoplasmosis, leishmaniasis and tuberculosis),
gene(s) modulating the T-helper type 1 and type 2 dichotomy
(leishmaniasis, leprosy and HIV infection) and the natural killer cell
complex (cytomegalovirus infection). There also have been other advances
in immunogenetics that have led to a better understanding of resistance
to intracellular pathogens. These include effector mechanisms of immune
response genes and factors modulating genetic susceptibility.
Identification of genes that determine resistance/susceptibility (and
their effector mechanisms) has impacted on vaccine development.
Immunogenetics has been important in characterizing roles of TCR genes,
superantigens, and host genes that play a role in molecular mimicry in
disease pathogenesis. In addition, recent work with gene knockout,
recombinant inbred or congenic, mutant, consomic, and transgenic mice,
positional cloning, mouse/human gene homologies to identify candidate
human resistance genes, and the rapid expansion of the gene
transcription maps of the human genome, have been important in analysis
of resistance to intracellular pathogens.
