This vaccine is used as a thread of teeth instead of needles

“The mucous surfaces are important, because they are a source of entry for pathogens, such as influenza and Wafid,” says Harverider Singh Jill, the author opposite the paper. “However, if a vaccine is given by injection, antibodies are produced primarily in the bloodstream throughout the body, and relatively few antibodies are produced on mucous surfaces.

Jill, a professor of the term Ronald B. “This improves the body’s ability to prevent infection, because there is an additional line of defending antibodies before the nurse enters the body.”

This is where the functional epithelium comes. The term epithelium applies to the tissues that are lined on the surface of the body parts, such as the lining of your lungs, stomach and intestine. Most epithelial tissues include strong barriers designed to maintain bad things – from viruses to dirt – from entering the bloodstream. But an epithelium is different.

The connection epithelium is a thin layer of tissues in the deepest part of the pocket between the tooth and gums, and lacks the features of the septum in the other epithelial tissues. The lack of a functional epithelium allows the release of immune cells to fight bacteria – you find these immune cells in your saliva, as well as between your teeth and gums.

“Since the functional epithelium is more accessible than other epithelial tissues – a mucous layer – it provides a unique opportunity to introduce vaccines to the body in a way that stimulates the production of reinforced antibodies through the mucous layers in the body.”

To determine the ability to provide vaccines via a detailed epithelium, the researchers applied the vaccine to the unxtured teeth thread and then briefly laboratory mice teeth. Specifically, the researchers compared the production of antibodies in mice that received the peptide flu vaccine by threading the connection epithelium; Through the nasal epithelium. Or by applying a vaccine on the sublime mucous tissue.

“We have found that the application of the vaccine through an interpowering epithelium results in a superior response to the antibodies on the mucous surfaces of the current golden standard of vaccination through the oral cavity, which included the placement of the vaccine under the tongue.” A student under the gills at Texas University of Technology. “The thread technology also provides similar protection against the influenza virus compared to the vaccine that is given through the nose epithelium.”

“This is very promising, because most vaccine combinations cannot be given by the nose epithelium – the barrier features in this mucous surface prevent the absorption of effective vaccine,” says generation. “Childbirth also has the ability to make the vaccine up to the brain, which can pose safety concerns. However, vaccination through functional epithelium does not provide any such risk. For this experiment, we have chosen one of the few vaccine combinations that already work to connect the nose because we want to see how to connect the traditional epithelium compared to the best scenario in the intention.

The researchers also tested whether the functional epithelium method works for three other prominent categories of vaccines: broken proteins, viruses and MRNA. In all three cases, the epithelial connection technique has produced strong responses to antibodies in the bloodstream and across mucous surfaces.

The researchers also found that at least in the animal model, it does not matter whether food and water were consumed immediately after the thread with the vaccine – the immune response was the same.

But while the normal thread is a sufficient way of connecting vaccines to laboratory mice, researchers know that it is not practical to ask people to keep the thread covered with the vaccine in their fingers. To address this challenge, researchers used a thread. The selection of the thread consists of a piece of thread extending between two parts that can be maintained by a handle.

Specifically, the researchers wrapped the thread in a thread chosen with a fluorescent food dye. Then the researchers recruited 27 participants in the study, explained the concept of applying the vaccine across the thread, and asked the participants an attempt to deposit the food dye in their epithelial intersection by choosing a thread.

“We have found that approximately 60 % of the dye was deposited in the gum pocket, indicating that the thread choices may be a practical way to connect vaccines to the epithelial intersection,” says Angol.

“We are optimistic about this work – and depending on the results we have reached – they may move towards clinical trials,” says Gil.

Although there are still many questions that must be answered before the thread technique is seen for clinical use, researchers believe that there may be important advantages that go beyond the response of improved antibodies to mucous surfaces.

“For example, it will be easy to manage, and it deals with concerns about many people about acupuncture.” We believe that this technology should be comparable to prices with other vaccine delivery techniques.

There are also some disadvantages. For example, this technique will not work on infants and young children who have no teeth yet.

“In addition, we will need to know more about how or if this approach will work for people with gum disease or other oral infections,” says Gil.
