This article discusses the evidence from animal experiments, infant-mother studies . relationship, that is, the presence of one inhibits the other”(p65). . other words we can now say that touch, not only affects the immune system but also . Main quotes a study by Anisfield (), which gives evidence that touch through. A well-developed immune system is essential for healthy pigs. Innate and adaptive immunity have a hand and glove relationship. The mucosal immune system is not well developed in the newborn pig and gradually Unfortunately, the maternal milk factors that control the immune response and. The relationship between the innate immune system versus the acquired natural birth, human infants are first colonized from maternal flora followed by Seifert () quotes references in the scientific literature to the resistance of.

Chronically high cortisol levels destroy tissue. Chronically elevated adrenalin levels raise the blood pressure and damage the heart. There is extensive documentation of the inhibiting effect of chronic stress on the immune system. In one study, the activity of immune cells called natural killer NK cells were compared in two groups: NK cells are front-line troops in the fight against infections and against cancer, having the capacity to attack invading micro-organisms and to destroy cells with malignant mutations.

The NK cell functioning of the caregivers was significantly suppressed, even in those whose spouses had died as long as three years previously. The caregivers who reported lower levels of social support also showed the greatest depression in immune activity — just as the loneliest medical students had the most impaired immune systems under the stress of examinations.

Another study of caregivers assessed the efficacy of immunization against influenza. In this study 80 per cent among the non-stressed control group developed immunity against the virus, but only 20 per cent of the Alzheimer caregivers were able to do so. The stress of unremitting caregiving inhibited the immune system and left people susceptible to influenza.

Research has also shown stress-related delays in tissue repair. The wounds of Alzheimer caregivers took an average of nine days longer to heal than those of controls. Higher levels of stress cause higher cortisol output via the HPA axis, and cortisol inhibits the activity of the inflammatory cells involved in wound healing. Dental students had a wound deliberately inflicted on their hard palates while they were facing immunology exams and again during vacation.

Interaction between innate and adaptive immunity

Active immunization through vaccines [ 13 ] and passive immunization through breast milk feeding [ 14 — 18 ] are immunological pathways that promote the maturity and development of the infant immune system.

Indeed, studies investigating neonatal protection against infection during lactation have shown that breast-feeding provides significant protection to growing offspring against diarrhea caused by V.

Additionally, epidemiological data have associated breast-feeding with reduced incidence of immune-mediated diseases such as celiac disease, at least in childhood [ 2021 ], and diabetes mellitus type I, but these findings need more research [ 22 ]. Historically, breast milk has been thought to pass immunity to the growing infant only by virtue of its immunoglobulin content [ 23 — 26 ].

Because breast milk antibodies exist in high amounts and are directed against the microbes the mother has met previously, they are poised to protect the growing infant against a wide array of microorganisms [ 2728 ].

More recent studies have shown that breast milk also contains additional components of the maternal immune system [ 29 — 34 ]. Indeed, a variety of maternal leukocytes are present in both colostrum and mature breast milk, with macrophages and neutrophils dominating over lymphocytes [ 34 — 38 ]. However, our understanding of the trafficking of these maternal leukocytes and the significance of their transmission to the suckling offspring is still limited.

Additionally, most of the previous studies employed non-physiological protocols of breast milk leukocyte inoculation into starved young infant animals, which exemplify neither the number nor the status of leukocytes physiologically found in breast milk [ 40414350 ].

In the current study, we sought to examine the physiological trafficking of maternal leukocytes to different organs of suckling pups and investigate the transfer of cellular immunity during lactation.

Our studies show that maternal leukocytes can be transferred to the pups via breast milk in a number of mouse fostering models. We found that CD8 T cells from the breast milk are taken up by the suckling infants and found in their PPs.

Breast milk is known to suppress rather than increase inflammatory responses in the infant [ 51 — 54 ]. Surprisingly, our investigation showed that transferred breast milk CD8 T cells exhibit functional superiority related to the production of pro-inflammatory and cytolytic mediators when compared to host counterparts. Animals were housed in temperature- water- and humidity- controlled cages that alternated between h light and dark cycles. Fostering of pups Three experimental models were used, and in all these settings, mice were coordinately mated: We do not know the exact explanation of this behavioral phenomenon, but we would assume that the difference in fur color may be a factor.

Organs from fostered pups were collected at Weeks 1—3 of nursing and at Weeks 1, 5, and 20 post-weaning for experimental assays. Because the yield of leukocytes isolated from PPs is time sensitive, we proceeded with the isolation quickly to obtain better cell viability. PPs were obtained from either a single mouse or combined pups, depending on age. The PPs were then dissociated by gently crushing the patches with the plunger of a 1 mL syringe, forcing them through the filter until they were no longer visible pieces of tissue.

This mechanical dissociation allowed for the isolation of non-adherent cells, such as B and T lymphocytes, as well as adherent cells, including monocytes and dendritic both of which require enzymatic treatment to be isolated. To study the phenotype and function of recovered PP T lymphocytes, we limited tissue processing to the mechanical dissociation because enzymatic tissue disintegration can have a profound impact on surface molecule expression and immune function [ 57 ].

Moreover, this enzymatic treatment is not required for T cell isolation [ 58 ]. Isolation of hematopoietic cells from the intestinal mucosa and other tissues PPs were excised; then, the small and large intestine was flushed with PBS and cut longitudinally along its length before being cut into smaller pieces. Intraepithelial cells were isolated from the pooled supernatants [ 5859 ]. Lamina propria cells were isolated from the pooled supernatants [ 5859 ].

Intraepithelial and lamina propria cells were pooled together referred as intestinal mucosa or IM and stained with antibodies for flow cytometry assays. The tissues were dissociated by gentle crushing with the plunger of a 1 mL syringe.
