Table 1 Mtb virulence factors counteracting the innate immune response. Murray PJ. Immunology : — Host cell death in immunity The mode of host cell death after Mtb infection is crucial for the outcome of the disease. Mtb is an extremely successful intracellular pathogen that has co-evolved with its host for eons. Eur J Immunol ; 42 : — Rab10 regulates phagosome maturation and its overexpression rescues Mycobacterium-containing phagosomes maturation. Front Microbiol ; 7 :
cells are uniquely positioned to determine the balance between protective and pathogenic.
The innate immune response in human tuberculosis
M ycobacterium tuberculosis (Mtb) infection can be cleared by the innate immune system before the initiation of an adaptive immune response. Innate Immune Responses to Tuberculosis.

pathogen of macrophages, with alveolar macrophages being the primary conduit of infection and disease.
The host innate immune response to TB requires a variety of different host cell types to successfully protect the host from infection.
MBio ; 5 : 4. Autophagy ; 12 : — Over-expression of superoxide dismutase obliterates the protective effect of BCG against tuberculosis by modulating innate and adaptive immune responses. J Immunol Res ; : PLoS Pathog ; 3 : e Infect Immun 59 : —
These immune cells recognize the TB-causing pathogen and measures also limit the development of adaptive immune responses during Mtb infection. The major innate immune cell types involved in Mtb infection include.
The different manifestations of infection with Mycobacterium tuberculosis Finally, the innate host response is necessary for induction of adaptive immunity to M.
IRGM gene polymorphisms and haplotypes associate with susceptibility of pulmonary tuberculosis in Chinese Hubei Han population.
Innate Immune Responses to Tuberculosis.
Advanced search. Annu Rev Physiol ; 79 : — Although cytosolic localization of Mtb has been reported in vitroless is known regarding the subcellular localization of Mtb in cells from patients with TB.
Mycobacterium tuberculosis suppresses innate immunity by coopting the host ubiquitin system.
innate immune responses through a process termed 'trained immunity', we hypothesize that losis (TB), which is one of the world's deadliest infectious dis.
Innate immunity in tuberculosis host defense vs pathogen evasion Cellular & Molecular Immunology
This demonstrates that the innate and adaptive immune response of the host in controlling TB infection is effective. Mycobacterial and host.
Front Microbiol 2 : It consists of i the epithelium, a layer of airway epithelial cells AECs forming a barrier that prevents invasion; ii the lamina propria, a layer of connective tissue and immune cells, including lymphocytes and macrophages; and iii a coating of a highly complex substance known as airway surface liquid ASLwhich contains mucus, immunoglobulin A and an array of other innate immune factors on the luminal surface.
Upon invading host cells through phagocytosis, Mtb can replicate within infected cells by arresting phagosome maturation. Tuberculosis ; 93 Suppl : S33—S It is clear from increasing experimental evidence and clinical observations that Mtb controls host innate immunity by dictating a sophisticated program that involves multiple host signaling pathways and cellular functions.

|Immunobiology ; : — We also describe evidence demonstrating that Mtb modulates the host innate immune defense functions to its own benefit. CLRs have been increasingly recognized to play an important role in modulating Mtb-mediated immune responses, and Mtb surface ligands, including ManLAM and cord factor, are important immune modulators that can be directly recognized by several CLRs.
