Tumor Immunology: Physiological Regulation - Sleep and Rest
Sleep and rest affect the immune system. Lack of sleep can have a detrimental effect on immune function. A complex feedback loop involving cytokines such as interleukin-1 and tumor necrosis factor involved in the immune response to infection also affects the regulation of REM and slow-wave sleep. Thus, the immune response to infection can affect the sleep cycle, in particular by increasing the relationship between slow-wave sleep and fast-wave sleep.
In people with sleep deprivation, active immunization has less effect, and antibody production is reduced compared to a rested person. In addition, insomnia and shift work due to disruption of natural light and darkness can affect proteins such as, for example, NFIL3, which is associated with T cell differentiation and circadian rhythm. Such disorders can lead to chronic diseases such as heart disease, chronic pain, and asthma.
Sleep and the associated circadian rhythm strongly regulate the immune functions of both the innate and acquired immune systems. In the early phase of slow-wave sleep, there is a drop in the levels of cortisol, adrenaline and norepinephrine in the blood, which causes an increase in the levels of hormones leptin, pituitary growth hormone and prolactin. These signals stimulate the pro-inflammatory environment by producing cytokines IL-1, IL-12, TNF- and INF. These cytokines promote the activation, proliferation, and differentiation of immune cells. At this time, undifferentiated and less differentiated immune cells (naive and central memory T cells) reach their peak during the slow-developing acquired immune responses. In addition to these effects, the hormones leptin, growth hormone, and prolactin support the interaction between APC and T cells, a shift in the balance between Th1/Th2 helpers on the side of Th1, the proliferation of Th helper cells, the migration of naive T cells to the lymph nodes, and probably also support the formation of long-term immune memory by triggering the T h 1 cell response.
On the other hand, differentiated effector cells such as cytotoxic natural killer cells and cytotoxic T lymphocytes (CTL) reach their peak during wakefulness. As a result, they can effectively respond to invading pathogens. There is also an increased concentration of anti-inflammatory molecules such as cortisol and catecholamines. There are two theories as to why a pro-inflammatory state occurs during sleep. Firstly, inflammation during wakefulness can lead to serious impairments of physical and mental abilities. In addition, more melatonin is present during sleep, which relieves oxidative stress (works against the formation of free radicals) due to the presence of inflammation.
Eating
Excessive intake of nutrients can lead to diabetes and obesity, which affect immune functions. Moderate malnutrition and a lack of certain minerals and nutrients can weaken the immune response.
Foods rich in certain fatty acids can strengthen the immune system.Malnutrition of the fetus can lead to a weakening of the immune system for life.
