The solution to the "deadly shock" puzzle can paralyze the body in a few minutes



Researchers say they have discovered how an allergic shock can cause a body dislocation within minutes.

Researchers found that exposing mice to small amounts of allergens stimulates various immune cells to work together.

The team at the University of Duke explained that this triggers a life-threatening allergic reaction.

In the new study, the researchers analyzed cells under a microscope and found some practical information about allergens that interact with others to stimulate the release of histamine.

Researchers suppressed various immune cells in mice before injecting them with toxins that cause hypersensitivity.

After analyzing the mice within half an hour, they found that mast cells that release histamine do not catch the allergens themselves.

But when researchers reduced the number of dendritic cells in mice, a component of the immune system, they did not suffer from allergies even after exposure to stimuli.

During the study of dendritic cells under the microscope it was found that they consist of long branches that penetrate other cells during the search for allergens.

When these cells recognize the allergen, small bubbles containing information are sent to the surrounding mast cells.

This method publishes information about gas allergens surrounding mast cells, which then begin to delay sensitivity by filling the blood with histamine flow.

But research first has to determine if the process itself is taking place in humans and see how useful cells are.

The study was published in the journal Science.

An allergic reaction occurs when the body misidentifies a harmless substance, such as nuts and oysters, as a dangerous toxic substance.

Therefore, the immune response to allergens is released, which can cause sneezing and itching in the eyes.

In rare and serious cases, an allergic reaction can lead to hypersensitivity that can lead to throat edema, difficulty in breathing and even loss of consciousness.

Currently, patients with potentially serious allergies are often treated by injecting adrenaline.
