Modern civilization is becoming more and more developed, which has produced many impacts on the environment. Due to changes in the environment, human beings have created many diseases of civilization, and allergies are just one of them.
According to statistics, the more highly industrialized the country, the higher the rate of allergies. Therefore, understanding and preventing allergies is a must-know topic for people today.
What is allergy <br>The so-called "allergy" is the abbreviation of "hypersensitivity". In this way, not only the original immune response cannot be effectively exerted, but it will also cause individual discomfort and even affect our physical health.
In order to explore the causes of allergies, let’s first get to know some nouns:
1. Immune cells: roughly divided into two categories, lymphocytes (T cells, B cells, NK cells) and phagocytes (monocytes and multinuclear granules).
Each cell has its own role:
Some are responsible for devouring foreign matter,
Some are responsible for secreting antibodies and so on,
Work together with each other to achieve the ultimate goal: eliminate pathogenic bacteria and maintain good health.
2. Antigen: Any substance that can cause an immune response is called an antigen, and it is commonly known as an "allergen" in terms of allergic reactions.
T cells closely related to allergies <br>Allergic reactions are mainly produced by T cells and NK cells, such as atopic dermatitis.
Regardless of the type of allergic reaction, lymphocyte T cells always play a very important role, among which T cells can be subdivided into T helper cells (Th cells), and the Th cell population is composed of Th1 and Th2 cells .
Under normal conditions, Th1 and Th2 in the body are in a state of balance and fight against each other. When Th2 cells are larger than Th1 cells, it is easy to activate giant cells to release IgE, and it is easy to form allergic constitution.
To put it simply, when the first-line immune cells (macrophages) come into contact with allergens, they start a series of message transmission, activate the second-line immune cells (T cells), and then cause severe immune responses through signal transmission and amplification , causing the body to begin to experience uncomfortable symptoms, which are called allergic reactions.
Common allergic reactions: allergic rhinitis, asthma, atopic dermatitis.
Common allergens (antigens): pollen, dust mites, seafood, drugs.
Simply put, specific lactic acid bacteria activate immune cells to guide T cells to Th1 and strengthen Th1 responses; or guide T cells to Treg to inhibit Th2 responses. The above two mechanisms restore the body to a state of balance, thereby improving and preventing allergies.
Allergies are caused by the imbalance of the immune system. In addition to drug treatment, the most effective way is to isolate the allergens, and use probiotics with special immune functions to adjust the immune system in the body, so that the response tends to balance, and eliminate internal and external troubles in one fell swoop. , not only adjust the body constitution, but also reduce the chances of allergies, infections, and inflammations, thereby enhancing the body's immunity and achieving the maximum benefit of probiotics.
