36 As concluded in a recent review on this topic, after identification of diminished bacterial diversity in the skin microbiome of atopic individuals with consecutive loss of anti-inflammatory and tolerogenic interleukin 10, substitution of these tolerance promoting innate immune signals using microbes or microbial components is a new and promising therapeutic strategy.
These microbial components are detected by innate signaling pattern recognition receptors (PRRs), among the best known and most versatile of which are the Toll-like receptors (TLRs).
Not only various microbial components are recognized by PRRs, but also many endogenous danger-associated molecular patterns (DAMPs), which are usually intracellular molecules that have reached the extracellular space, either actively or passively following cellular damage or death.
We identify an lncRNA pseudogene, Lethe (named after the mythological river of forgetfulness, for its role in negative feedback), which is expressed in response to proinflammatory cytokines TNFα and IL-1β, and the anti-inflammatory agent, dexamthasone, but is not responsive to microbial components, and is primarily found on the chromatin.
The presence of microbial components often is associated with environmental and household cleanliness, however the hygiene hypothesis postulates that the lack of exposure to these pathogens at a young age increases susceptibility to allergen sensitization, accounting for the dramatic increases in allergic diseases in the developed world [ 5, 6].
It was notice that distinguished microbial diversity and component were detected between Reactor I and Reactor II, while Reactor II had similar genus component with Reactor III.
We have surveyed the literature for evidence in which a microbial component has indeed been observed to be an accompaniment of, and probably a major contributory factor to, a variety of (typically inflammatory) diseases that are normally considered 'non-communicable'.
Serological response to various microbial components might be considered as a universal marker for the enhanced translocation of gut microflora or a reflection of compromised mucosa immunity.
Protein-like and microbial humic-like components were relatively more enriched for the impoundment-affected sites compared to the upstream locations, in which terrestrial humic-like component was more dominant.
One key microbial component of the rhizosphere is the arbuscular mycorrhizal fungi (AM fungi), which can form symbiotic relationships with the majority of terrestrial plant roots [ 1].
