The function of the gut microbiome and the bidirectional communication between the gastrointestinal tract (GIT) and the brain is increasingly recognized in health and disease and disruption in its composition is not unique to the autistic pathology. However, the bidirectional communication between the gut and the brain, “the gut-brain/brain-gut axis” in autism has been relatively understudied. ...
Gut microbial communities can greatly affect host health by modulating the host's immune system. For many important insects, however, the relationship between the gut microbiota and immune function remains poorly understood. Here, we test whether the gut microbial symbionts of the honey bee can induce expression of antimicrobial peptides (AMPs), a crucial component of insect innate immunity. We...
As sequencing technology makes data generation faster, cheaper, and more comprehensive, studies of gut microbial communities are multiplying at an astonishing rate. As a result, our understanding of the host-gut microbe relationship is constantly improving. Studies to date have demonstrated that the gut microbiota contributes to host nutrition, health and behavioral patterns by providing energy...
BACKGROUND The gut is a major reservoir for human immunodeficiency virus (HIV) in patients receiving antiretroviral therapy (ART). We hypothesized that distinct immune environments within the gut may support varying levels of HIV. METHODS In 8 HIV-1-positive adults who were receiving ART and had CD4(+) T cell counts of >200 cells/μL and plasma viral loads of <40 copies/mL, levels of HIV and T...
The Campylobacter jejuni-host interaction may be affected by the host's gut microbiota through competitive exclusion, metabolites, or modification of the immune response. To understand this interaction, C. jejuni colonization and local immune responses were compared in chickens with different gut microbiota compositions. Birds were treated with an antibiotic cocktail (AT) (experiments 1 and 2) ...
Purpose The purpose of this study was to evaluate mechanisms controlling secretory IgA (SIgA) production, thereby ensuring maintenance of ocular surface health. Methods To determine whether the presence of specific gut commensal species regulates SIgA levels and IgA transcripts in the eye-associated lymphoid tissues (EALT), specific-pathogen-free (SPF) Swiss Webster (SW) mice were treated wit...
Transferring gut microbiota from one individual to another may enable researchers to "humanize" the gut of animal models and transfer phenotypes between species. To date, most studies of gut microbiota transfer are performed in germ-free mice. In the studies presented, it was tested whether an antibiotic treatment approach could be used instead. C57BL/6 mice were treated with ampicillin prior t...
Partially fed (4 -5 days) H .a. anatolicum (Iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (GS), gut membrane antigen (GM), triton extracted gut membrane antigen ( TX-GM ) and sodium dodecyl sulphate treated Triton extracted gut membrane antigen (SDS-TX-GM). The New Zealand white rabbits were immunized with GS, GM, TX- ...
Gut microbial ecology and function are dynamic in infancy, but are stabilized in childhood. The 'new friends' have a great impact on the development of the digestive tract and host immune system. In the first year of life, especially, the gut microbiota dramatically changes through interactions with the developing immune system in the gut. The process of establishing the gut microbiota is affec...
