The behavioral immune system is a phrase coined by the psychological scientist Mark Schaller to refer to a suite of psychological mechanisms that allow individual organisms to detect the potential presence of infectious parasites or pathogens in their immediate environment, and to engage in behaviors that prevent contact with those objects and individuals.
These abnormalities and the failure of the adaptive systems to resolve inflammation affect the well-being of the individual, including behavioral parameters, quality of life and sleep, as well as indices of metabolic and cardiovascular health, developing into a "systemic anti-inflammatory feedback" and/or "hyperactivity" of the local pro ...
Inflammation is a generic response, and therefore is considered a mechanism of innate immunity, whereas adaptive immunity is specific to each pathogen. [3] Inflammation is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out ...
The relationship between inflammation and depression is also seen across the lifespan, with inflammation at one point being associated with an increased risk of depression later in life. [8] This has been seen in relatively short periods with both adult men and women with high levels of inflammatory markers experiencing increased risk of ...
In people with fatty liver with associated inflammatory injury (steatohepatitis) blood tests are usually used to rule out certain types of viral hepatitis and autoimmune diseases. Low thyroid activity is more prevalent in people with NASH, which would be detected by determining the thyroid-stimulating hormone. [68]
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention.

The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis , which is characterized by severe inflammatory or immune responses of the host organism to pathogens.
Leukocytosis is a condition in which the white cell count is above the normal range in the blood. [1] [2] It is frequently a sign of an inflammatory response, [3] most commonly the result of infection, but may also occur following certain parasitic infections or bone tumors as well as leukemia.
