Asthma and atopy are characterized by T(H)2-type patterns of inflammation. The hygiene hypothesis suggests that early-life environmental exposure to microbes, other pathogens, and their products promotes innate immune responses that suppress atopy; the current epidemic of allergic disease may result from a dearth of such stimuli. Antiatopic responses engendered by these exposures include both T(H)1-type and regulatory-type patterns, the latter including mechanisms of antigen-presenting cells as well as those of lymphoid origin, and are characterized by prominent IL-10 and/or TGF-beta effects. The Toll-like receptors are an important family of innate immune response elements that have many similar structural and functional properties, but have evolved to recognize distinct ligands as well as to be expressed differentially on immune cells. An active and productive area of current research is investigating the utility of microbes and microbial products for modulation of inflammation in asthma and atopic disorders. Clinical trials have been conducted for some of these biologic compounds, such as cytosine-guanine dinucleotide DNA and Mycobacterium vaccae, whereas others remain in preclinical testing.

The production of traditional agave spirits in Mexico, such as mezcal, involves a process that uses environmental microorganisms to ferment the cooked must from agave plants. By analysing these microorganisms, researchers can understand the dynamics of microbial communities at the interface of natural and human-associated environments. This study involved 16S and ITS amplicon sequencing of 99 fermentation tanks from 42 distilleries across Mexico.

The slope aspect is an important environmental factor, which can indirectly change the acceptable solar radiation of forests. However, the mechanism of how this aspect changes the underground ecosystem and thus affects the growth of aboveground trees is not clear. In this study, Pinus yunnanensis plantation was taken as the research object, and the effects of soil and microbial characteristics on tree growth under different slope aspects and soil depths were systematically analyzed.

Global warming has threatened all-rounded hierarchical biosphere by reconstructing eco-structure and bringing biodiversity variations. Pacific white shrimp, a successful model of worldwide utilizing marine ectothermic resources, is facing huge losses due to multiple diseases relevant to intestinal microbiota (IM) dysbiosis during temperature fluctuation. However, how warming mediates shrimp health remains poorly understood.

Recalcitrant bacterial infections can be caused by various types of dormant bacteria, including persisters and viable but nonculturable (VBNC) cells. Despite their clinical importance, we know fairly little about bacterial dormancy development and recovery. Previously, we established a correlation between protein aggregation and dormancy in Escherichia coli.

Oxidative stress, caused by excessive production of reactive oxygen species (ROS), plays a crucial role in the occurrence and development of various diseases. Monascin can scavenge ROS and alleviate oxidative stress but with a low fermentation rate and bioavailability. Here, we optimized the fermentation process to increase the production of monascin (508.
