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...

In vivo Imaging Method to Distinguish Acute and Chronic Inflammation

We describe a non-invasive imaging method for distinguishing inflammatory stages. Systemic delivery of luminol reveals areas of acute inflammation dependent upon MPO activity in neutrophils. In contrast, injection of lucigenin allows for visualization of chronic inflammation dependent upon Phox activity in macrophages.

A Method to Induce Ocular Surface Inflammation in a Murine Model

This video demonstrates a method to induce ocular surface inflammation and meibomian gland dysfunction in a murine model. Stimulation of the mouse's immune system using an immunogen and later restimulation with the same immunogen promotes ocular surface inflammation, which causes plugging of meibomian gland secretion through neutrophil-produced aggNETs and leads to dry eye disease.

Although Candida infection models are available to study host immune resistance, a model to study T cell mediated immunopathology in the context of Candida infection is absent. Here we describe a method to establish Th17 immunopathology associated with oral Candida infection in immunodeficient mice.
FAQs
Recognition of microbial molecules or danger signals activates intracellular signaling cascades inside immune and affected tissue cells. These cascades include NF-κB and inflammasome activation, which stimulate production of cytokines, chemokines, and other mediators. The resulting signals connect the initial detection event to vascular changes, leukocyte recruitment, pathogen containment, and the beginning of tissue repair.
NF-κB and inflammasome activation are intracellular responses that follow recognition by innate immune receptors. In the described signaling network, they contribute to induction of cytokines, chemokines, and other inflammatory mediators. Examining these pathways helps researchers determine how an initial microbial or danger signal is converted into coordinated immune activity rather than an isolated cellular response.
Inflammatory signaling supports pathogen control and initiates repair when appropriately regulated, but persistent or dysregulated activity can produce harmful consequences. Continued mediator production, vascular effects, and leukocyte guidance may sustain inflammation after the protective response should resolve. This shift helps explain why the same signaling network is relevant to chronic inflammation and tissue injury research.
The response begins when innate immune receptors detect either microbial molecules or danger signals associated with tissue damage. That distinction links the upstream stimulus to activation of intracellular cascades and release of immune mediators. Studying these initiating signals can clarify how inflammation responds to infection while also revealing pathways that become activated during noninfectious tissue injury.
Pathway studies can connect microbial recognition with cytokine and chemokine production, vascular changes, and leukocyte movement into affected tissue. In infectious disease research, this supports analysis of how responses contain pathogens. In vaccine research, examining these signals provides context for understanding immune activation, although the overview does not specify particular vaccine designs or experimental measurements.
A useful conceptual workflow follows the sequence from the initiating microbial or danger signal, through receptor-linked intracellular cascades, to mediator production and tissue effects. Researchers can then relate leukocyte guidance and vascular permeability to pathogen containment, repair, chronic inflammation, or tissue injury. This pathway-based interpretation links molecular activity with outcomes relevant to immunology and infection.
The pathway network identifies molecular steps that connect immune detection with cytokines, chemokines, vascular changes, and leukocyte recruitment. When signaling becomes dysregulated or persistent, those steps are associated with chronic inflammation and tissue injury. Consequently, mapping the network supports research into inflammatory disorders and helps provide a rationale for developing therapies directed at specific signaling processes.
