Immunity is the body's owndefense mechanismThe human body recognizes and eliminates the foreigninvasionAny foreign matter(Viruses、Bacteria、parasite[5]Etc.), processingbe senile、damage、death, denatured autologous cells, and the ability to recognize and process mutant cells and virus infected cells in vivo.
modernimmunologyIt is believed that immunity is the ability of the human body to recognize and eliminate "dissidents"Physiological response。The body performs this functionimmune system。[1]
The immune characteristics of newborns often show that the immune system is not mature enough, the function is not perfect, and has not been exposed touterusExternal environmentAnd has not been exposed to a wide variety of food proteinsantigenicitySubstance.Pregnancy is affected by maternal antibodies that pass through the placenta, resulting in physiological hypoimmunity of the newborn.canStrengthen immunityThere are many ways to do this, among which the simple one is to pay more attention to zinc supplementation at ordinary times, and eat more walnuts, egg yolksOysters, seafood and other zinc rich foods.
The biggest threat to people's healthCardio cerebrovascular disease、diabetes、cancer, Chronicrespiratory diseaseThey are all related to immunity. "Enhancing immunity" cannot prevent such diseases.For example, when discussing the pathogenesis of cancer, we also said that "the elderlyDecreased immunity”It is prone to cancer, but the "immunity" related to cancer is dominated by the thymuscellular immunity,thymusyessternumThe back gland is the size of a chestnut, which producesThymosinIt supports the cellular immune function that inhibits the occurrence of cancer.The atrophy of thymus and the decline of cellular immune function after middle age is one of the reasons for the high incidence of cancer in middle-aged and elderly peopleprevent infection. Infectious diseases belong to“humoral immunity”Immunity is not the same thing.
With the development of medical research, in recent years, it has been found that there is a large category of diseases related to immune dysfunction. Such patients are not very immune and will not have anyInfectious DiseasesInfectious diseases, but because of the body's immune function, it is not suitable to produce many "anti"“antibody”, such as anti skin antibodies“lupus”, antiArticular cartilageAntibodies against TNF damage patients' joints, etc.“The flood washed the Dragon King Temple”The human body gets sick because of this, and the treatment of this kind of disease is difficult, more difficult or hopeless.

The body with low immunity is easy to be infected or suffer from cancer, and the abnormal immunity will also produce harmful results to the body, such asAnaphylactic reaction、Autoimmune diseaseEtc.
For various reasonsimmune systemCan not play a protective role normally, in this case, it is very easy to lead to bacterial, viral, fungal and other infections, so the most direct manifestation of low immunity is easy to get sick.Due to frequent illness, the consumption of the body is increased, so the body is generally weakinnutrition、Mental malaise, fatigue, loss of appetiteSleep disordersIt is common to get sick, take injections and medicine.It takes a long time to recover from each illness, and it often happens repeatedly.In the long run, it will lead to physical and mental dysplasia, and is also easy to induceMajor diseases。
The underlying cause is low immunity or incomplete immunity.When the immune function of the human body is dysfunctional or the immune system is not perfect, the following problems will recur: repeated attacks of coldsamygdalitisRecurrent attacksasthmaRecurrent attacksbronchitisRecurrent attackspneumoniaRecurrent attacksdiarrheaRepeated attacks must not be underestimated.

survey
Deficiency of endogenous peptides in human body can causeLow immune function, due to the low immune function, the body is in an unresponsive state, and the cold virus rushes in, leading to concurrent infection, especially epidemiccoldThe complicated infection is very serious,mortalityIt's also very high.With modern timesimmunologyThe relationship between peptide and immunity has gradually been fully understood.Insufficient peptide in human body can causeimmune organ Hypoplasia、atrophy, Yescellular immunity, humoral immunitycomplementFeatures anddevourThe role and other aspects have an important impact.
Thymus and lymph nodes
polypeptideinnutritionThe first organs and tissues to be injured arethymusandlymphoid tissue。Thymus reduced in size and weight, cortex andmedullaThe boundary is unclear, and the number of cells decreases.Spleen andlymph glandSize, weightorganization structure、cell densityAnd components also have obvious degenerative changes.If there is infection, the lymph tissue will go furtheratrophy。Experiments prove that when given peptidesNutritional deficiencyThe thymus tissue could return to normal after 60% of the animals were supplemented with peptide nutrition.
cellular immunity
Cellular immunity refers toT lymphocytesImmunity participating in the formation.When polypeptide nutrition is deficient, thymus and other tissues atrophy,T cellThe growth of is affected.The decline of cellular immune function is not only manifested in the reduction of T cell number, but also in the occurrence of functionobstacle。
humoral immunity
Humoral immunity refers toB lymphocytesParticipated in formationimmune。When the human body lacks peptide protein nutrition,Peripheral bloodMedium BCellsThe number ofunchanged。The functional experiment shows that no matter how difficult the peptide nutrition is,serumThe concentration of IgG is normal or slightly higher, especially when it is accompanied by infection. The production of IgG is affected and reduced in the absence of peptide, which is of great significance to the defense function of antibodies.
Phagocyte
Severe peptide protein nutritional deficiency, neutralwhite blood cellThe total number remains the same, but its function remains the same.CellularChemotaxisNormal or slightly slow down, normal phagocytosis, only for cellsEndocytosisThe killing ability of the incoming microorganisms is weakened.If peptide is supplemented in time, one or two weeks laterPhagocyteThe function can be recovered gradually.
Other immune systems
polypeptideIn case of active nutrition deficiency, some non-specific defense abilities also have significant changes, such as decreased lysozyme activity in plasma, tears, saliva and other secretions, and mucous membraneepithelial cellsTissue deformation, mucosal recruitment andCiliary movementChange,interferonDecreased production, etc., can affect the host's susceptibility to infection.
