Vascular calcification is an important predictor of and contributor to human cardiovascular disease. This protocol describes methods for inducing calcification of cultured primary vascular smooth muscle cells and for quantifying calcification and macrophage burden in animal aortas using near-infrared fluorescence imaging.

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 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.

This video demonstrates the induction of systemic inflammation in an anesthetized mouse. The injection of mycobacterial antigen-adjuvant depots triggers cytokine release and localized inflammation. Lymphatic vessels open, enabling immune cell entry into lymph nodes and activation of T cells, which release pro-inflammatory cytokines, leading to widespread inflammation.

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
After muscle damage, inflammatory signaling coordinates several linked responses rather than acting as a single event. Signals recruit immune cells, increase local blood flow, and promote mediator release. Together, these changes help clear damaged components and create conditions for repair. The sequence is therefore important because inflammation can support recovery when it remains appropriately regulated.
Persistent muscle inflammation changes the clinical significance of an initially protective response. Continued immune activity and mediator release can interfere with normal muscle function and contribute to disease, rather than simply resolving after tissue repair begins. This distinction matters in medicine because restoring muscle health requires supporting repair while limiting the tissue damage associated with chronic inflammation.
Different initiating stresses can lead to the same broad inflammatory response in skeletal muscle. Tissue injury, infection, and cellular stress are all identified as possible triggers, but their presence does not by itself establish a specific diagnosis. Clinicians therefore interpret inflammatory findings in context, distinguishing a general response from conditions such as myositis or autoimmune disease.
Assessment typically combines clinical findings with laboratory tests and imaging, with biopsy used in some cases. These sources provide complementary evidence rather than a single definitive measure: clinical evaluation identifies relevant findings, tests support assessment, imaging examines muscle, and biopsy can supply tissue-level information. The combined approach helps clinicians evaluate suspected inflammation and guide further medical decisions.
In medicine, evaluating muscle inflammation is relevant when clinicians investigate myositis, autoimmune disease, or exercise-related injury. The same assessment framework can therefore serve different clinical questions, from identifying disease-associated inflammation to evaluating muscle after exertion or injury. Interpreting the findings alongside the clinical situation helps connect evidence of inflammation with diagnosis and management.
Findings from the evaluation can inform more than diagnosis. They may help guide treatment selection and rehabilitation, while also contributing to research on therapies designed to restore muscle health without prolonging tissue damage. This makes assessment clinically useful at multiple stages, from recognizing a problem to planning recovery and studying how inflammatory control affects muscle outcomes.
