Pulmonary tuberculosis is currently considered a serious health problem worldwide. To understand tuberculosis infection we need to know the interaction between the host's immune response and the microorganism causing tuberculosis. Ample research has been carried out to identify new molecules and genes involved in the evasion mechanism of the host's immune response. This knowledge has generated the possibility that future therapeutic schemes will be designed to fight these particular molecules or genes. We reviewed recent experimental evidence on the mechanisms that will successfully fight against mycobacteria.

UI MeSH Term Description Entries
D009169 Mycobacterium tuberculosis A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation. Mycobacterium tuberculosis H37Rv
D009336 Necrosis The death of cells in an organ or tissue due to disease, injury or failure of the blood supply.
D010588 Phagosomes Membrane-bound cytoplasmic vesicles formed by invagination of phagocytized material. They fuse with lysosomes to form phagolysosomes in which the hydrolytic enzymes of the lysosome digest the phagocytized material. Phagolysosomes,Phagolysosome,Phagosome
D005802 Genes, MHC Class II Genetic loci in the vertebrate major histocompatibility complex that encode polymorphic products which control the immune response to specific antigens. The genes are found in the HLA-D region in humans and include H-2M, I-A, and I-E loci in mice. Class II Genes,Genes, Class II,Genes, HLA Class II,MHC Class II Genes,Class II Gene,Gene, Class II
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D017209 Apoptosis A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, i.e., DNA FRAGMENTATION. It is genetically programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth. Apoptosis, Extrinsic Pathway,Apoptosis, Intrinsic Pathway,Caspase-Dependent Apoptosis,Classic Apoptosis,Classical Apoptosis,Programmed Cell Death,Programmed Cell Death, Type I,Apoptoses, Extrinsic Pathway,Apoptoses, Intrinsic Pathway,Apoptosis, Caspase-Dependent,Apoptosis, Classic,Apoptosis, Classical,Caspase Dependent Apoptosis,Cell Death, Programmed,Classic Apoptoses,Extrinsic Pathway Apoptoses,Extrinsic Pathway Apoptosis,Intrinsic Pathway Apoptoses,Intrinsic Pathway Apoptosis
D057131 Immune Evasion Methods used by pathogenic organisms to evade a host's immune system. Evasion, Immune,Evasions, Immune,Immune Evasions
