Tumor necrosis factor (TNF) protects against infection, which means that inhibiting it can cause latent infections to resurface. TNF is a substance in the immune system, which is an important in activating chronic diseases. TNF inhibitors are a form of treatment for patients with rheumatoid arthritis and certain bowel diseases. Researchers have now discovered a new mechanism, TNF protects against intracellular pathogens that cause infection.
To defend the body against intracellular pathogens, such as the single-cell parasites Leishmania, nitric oxide (NO) must be produced. This is formed in macrophages and other phagocytes through type 2 NO synthase (NOS2). However, the function of NOS2 is inhibited by a competing enzyme called Arginase.This causes nitric oxide production to increase and suppresses the pathogens.
They are confirmed in ongoing experiments with human cells, these findings provide a plausible explanation of the increased susceptibility to infection that occurs during anti-TNF treatments, concurrent use of Arginase inhibitors could minimise the risk of infection associated with TNF.'
Tumour necrosis factor-alpha (TNF-α) is a central signalling substance of the immune system and involved in many inflammatory processes. Blocking this molecule is the treatment against many a inflammatory diseases
The reference of the above explanation is that the molecular mechanism which the release of TNF-α is based was first clarified by a working group from the Cluster of Excellence "Inflammation at Interfaces" at the Faculty of Medicine at Kiel University. The team, led by cell biologist Professor Karina Reiß, therefore achieved a pioneering success. This is because the principle discovered is of fundamental significance and opens up research in cell biology. Apart from this, the study which was recently published in Nature Communications identifies new starting points for the development of anti-inflammatory treatments.
What are the roles of TNF in the body defense against infection. Please include reference.
in terms of innate immunity what is the body's second line of defense against microbial infection/disease? explain the roles of the formed elements in the blood, lymphatic system, and phagocytes.
Explain why the blood is sometimes called the second line of defense against infection. Include the various blood components and how they perform this function.

Mycobacterium tuberculosis is an intracellular pathogen that grows within macrophages. Explain how the defense against this pathogen will be organized and what type of cells will be activated to fight the infection. Please include in your answer which MHC will be involved and what will follow after that (meaning what type of T cells will be engaged in the process)
