Overview In response to tissue injury and infection, mast cells initiate inflammation. Mast cells release chemicals that increase the permeability of adjacent blood capillaries and attract additional immune cells to the wound or site of infection. Neutrophils are phagocytic leukocytes that exit the bloodstream and engulf invading microbes. Blood clotting platelets seal the wound and fibers create a scaffold for wound healing. Macrophages engulf aging neutrophils to end the acute inflammatory...

We describe a rat model of post traumatic stress disorder (PTSD) that reveals the persistent alterations in neuroendocrine function and the delayed long-term, exaggerated fear response, characteristic of PTSD patients. The animal model and methods described here are useful for correlating biomarkers in brain nuclei, which are mechanistic but cannot be measured in patients, with biomarkers in peripheral white blood cells, which can.

Source: Laboratory of Jeff Salacup - University of Massachusetts Amherst Throughout this series of videos, natural samples were extracted and purified in search of organic compounds, called biomarkers, that can relate information on climates and environments of the past. One of the samples analyzed was sediment. Sediments accumulate over geologic time in basins, depressions in the Earth into which sediment flows through the action of fluid (water or air), movement, and gravity. Two main types...

Source: Laboratory of Jeff Salacup - University of Massachusetts Amherst The material comprising the living "organic" share of any ecosystem (leaves, fungi, bark, tissue; Figure 1) differs fundamentally from the material of the non-living "inorganic" share (rocks and their constituent minerals, oxygen, water, metals). Organic material contains carbon linked to a series of other carbon and hydrogen molecules (Figure 2), which distinguishes it from inorganic material. Carbon's wide valency range...

Source: Laboratory of Jeff Salacup - University of Massachusetts Amherst Every lab needs standards that track the performance, accuracy, and precision of its instruments over time to ensure a measurement made today is the same as a measurement made a year from now (Figure 1). Because standards must test the performance of instruments over a long period of time, large volumes of the standards are often required. Many chemical standards can be purchased from retail scientific companies, like...
FAQs
Tissue injury or infection activates innate immune pathways, which then stimulate transcriptional programs in responding cells. These programs increase production of inflammatory mediators, including cytokines and acute-phase proteins. Measuring the resulting molecular changes can help characterize the intensity or biological context of immune activation and connect an observed inflammatory state with the underlying response.
Genetic variants may affect inflammation biomarkers at several levels. A variant can influence how much of a mediator is produced, how its expression is regulated, or how cells respond to its signaling. These differences can create inherited variation in measured inflammatory profiles, helping researchers investigate why individuals show different susceptibility or biological responses in related conditions.
Biomarker measurements provide evidence of an inflammatory response, whereas genomic data can identify inherited factors that influence that response. Considering both types of information helps researchers connect molecular signals with genetic susceptibility and disease mechanisms. This combined perspective also supports efforts to separate inherited effects from environmental influences that may produce similar inflammatory findings.
Researchers can interpret biomarker patterns alongside genomic information to assess whether differences in inflammatory activity are associated with inherited variation. This comparison does not treat every measured signal as genetic; environmental influences may also contribute to the same phenotype. Separating these possibilities improves the interpretation of susceptibility, disease mechanisms, and variation among individuals or study groups.
A genetics study can measure inflammatory signals such as cytokines or acute-phase proteins and analyze those results together with genomic data. Researchers then examine relationships between biomarker variation, genetic differences, and the condition under investigation. This integrated workflow helps identify susceptibility factors and characterize mechanisms rather than relying on either molecular measurements or genetic information alone.
These biomarkers are useful when researchers need to characterize immune activity across autoimmune disease, infection, or complex disorders. In combination with genomic data, they can support patient stratification, risk assessment, and investigation of disease mechanisms. The resulting information may also guide development of targeted therapies by linking inflammatory patterns with susceptibility or clinically relevant biological differences.
