Worms conspire with gut microbes

Worms conspire with gut microbes

 

Intestinal worms manipulate their host’s immune system to ensure their survival,in part by changing the metabolism of the host’s gut microbiome.

     The worms,calledhelminths,infect around 2 billion people around the world,and are able to block harmful inflammatory responses in humans and mice .Nicola Harris at the Swiss Federal Institute of Technology in Lausanne and her colleagues studied mice infected with the helminth Heligmosomoides polygyrus bakeri,and found that mice that had been treated with antibiotics to kill gut bacteria before being exposed to the worms had more allergic airway inflammation than did untreated,worm-fected animals.Worm infection caused the microbiota to produce increased levels of short-chain fatty acids in mice,pigs and six out of eight human volunteers.The anti-inflammatory effects of worm infection were lost in mice that had been engineered to lack a receptor for the fatty acids.

The findings suggest that helminths and gut microbes have evolved this mechanism to regulate the host immune system over many millions of years,the authors say.

Could not find the product you are looking for in our website? Please do not worry! We provide product customization service according to your needs.Product Customization Service

Select the appropriate stage customizable service (above image). We validate at every step to fulfill special needs of researchers.

We provided the service for some of our customers and got a very good feedback. 

For example, one of our customer needs C1QBP antibody for WB.  He just needs to provide us the details for the targeted antigen and our R&D Department develops the required antibody in 3 months.

WB

On demand but unavailable ELISA kits are subject to special development as well. We design the AA peptide according to your needs and carry it through a prokaryotic expression system. Then we get the antibody and verify it by SDS-PAGE, WB or Immunochemistry. Only the verified antibody will be developed in ELISA Kits. Before shipment, all the Kits are submitted to samples testing and only qualified products will be sent to the customer along with all the data sheet.

We do the research for you!

Preparation of the Standard

1.Preparation of Standard

Prepare standard is a very difficult and complicated step during the labeled immunoassays. Following are talking about how to produce standard for laboratory and business.

  Matrix Preparation. Matrix of the standard should be as same as tested sample. The serum without under-test materials should be used for produce some standards which can determine specific substance in serum. This can supply a suitable medium environment for reaction. Because zero-serum is difficult to made, some suitable buffer can be use for standards’ production. Adding carrier protein (usually is 1%~2% Albumin Bovine) in buffer to make the medium environment similar with the sample.

  Methods for zero-serum production

  1. Adsorption: Using carbon to remove some small molecules in serum, such as T3, T4. Although the process is very simple, clear of tested materials absolutely is difficult. Furthermore, macromolecular substances cannot be made by this way.
  2. Repeated freeze-thaw method: Low-value serum can be chosen for macromolecular substances production. Repeated freeze-thaw can make the materials inactive. This method can lead some protein hormone out of activity. But is still difficult to get the real zero-serum.

  Affinity chromatography

Use specific antibody to produce Affinity Column. This can absorb tested antigen. This method can get a high quality zero-serum but it’s complicated and need a high cost.

  How to choose pure standards. The standards should choose the materials with high CP and immune pure. The immune pure is more important than CP. The material which has cross-reactive with tested materials should not be included in standard.

  Produce Standards

Produce high concentrated standards by using zero-serum. According to the laboratory’s requirement, produce series standards which composed by differe......
