This video demonstrates the staining and preparation of bacterial cells for immunological studies using red fluorescent dye. The stained bacteria are diluted and resuspended in a growth medium to achieve the desired bacterial concentration for host cell infection, representing the multiplicity of infection.

Supported planar bilayers are powerful tools that can be used to model the molecular interactions in an immunological synapse. Here, we show methods for anchoring cell adhesion proteins known to modulate synapse formation to the upper leaflet of the lipid bilyer and visualize synapse formation using TIRF microscopy.

This opsonophagocytic killing assay is used to compare the ability of phagocytic immune cells to respond to and kill bacteria based on different treatments and/or conditions. Classically, this assay serves as the gold standard for assessing effector functions of antibodies raised against a bacterium as opsonin.

Visual analytics (VA) is a new approach of analyzing data interactively. In this video, we discuss the data overload problem brought on by high-throughput biological experiments, and propose VA as a solution to such problem. The video demonstrates analysis within and between immunological datasets using a VA tool called Tableau.
FAQs
Antigen recognition provides the immune system with a basis for distinguishing relevant foreign or altered targets, while antigen presentation helps communicate that information to responding immune cells. Studying both processes together reveals whether a response is initiated effectively and whether later events, such as lymphocyte activation and antibody production, follow appropriately under defined experimental conditions.
Innate and adaptive mechanisms provide complementary information about immune activity. Their coordinated evaluation can show whether early detection and signaling are followed by targeted lymphocyte responses and antibody production. This comparison helps researchers determine whether immunity is activated as an integrated process or whether disruption occurs at a particular stage of the response.
Cytokine signaling helps coordinate communication during an immune response, whereas lymphocyte activation indicates that adaptive immune cells have responded to the relevant stimulus. Measuring these features can clarify whether signaling is sufficient to promote downstream activity, including antibody production. Their patterns also help identify responses that are weak, excessive, or otherwise dysregulated.
Researchers compare cellular or molecular responses measured under defined conditions with the expected pattern of coordinated immune activity. Evidence of antigen recognition, signaling, lymphocyte activation, or antibody production can indicate activation, while altered or incomplete patterns may suggest disruption. This approach supports analysis of immune deficiency, inflammation, autoimmunity, allergy, or other disease-related changes.
A study begins by selecting a defined biological condition involving a pathogen, foreign substance, altered cell, or immune-related state. Researchers then measure relevant cellular or molecular responses, including signaling, lymphocyte activity, or antibody production, and interpret the results in relation to immune activation or regulation. The workflow can be adapted to characterize health and disease.
Possible outcomes include the extent of antigen recognition, antigen presentation, cytokine signaling, lymphocyte activation, and antibody production. Together, these measurements describe how effectively immunity is initiated, coordinated, and regulated. Comparing such outcomes across defined conditions can help characterize infection, inflammation, vaccination, allergy, autoimmunity, or immune deficiencies without relying on a single immune indicator.
They are useful when researchers need to determine how immune activity changes in response to a defined condition or intervention. Results can show whether immunity is activated, regulated, or disrupted, supporting evaluation of vaccination responses and the characterization of disease-related immune patterns. The same evidence can inform diagnostic development and immune-based therapeutic research.
