With effector functions distinct from other T cell subsets, Th17 cells have been centrally implicated in inflammatory autoimmunity. This in vitro Th17 differentiation protocol provides a means to determine whether naïve CD4+ T lymphocytes can differentiate into Th17 cells, and to further examine their role in autoimmunity and host response.

Here a protocol is presented to measure bacterial capture by CD4+ T cells which occurs during antigen presentation via transinfection from pre-infected dendritic cells (DC). We show how to perform the necessary steps: isolation of primary cells, infection of DC, DC/T cell conjugate formation, and measurement of bacterial T cell transfection.

The video demonstrates an immunological method to monitor in vivo adjuvant-induced cytotoxic T lymphocyte or CTL production. A mouse is pre-injected with genetically engineered, proliferative dye-stained donor CD8+ T lymphocytes. Subcutaneous injection of ovalbumin with adjuvants generates cytotoxic CD8+ T lymphocytes that are identified post-harvesting through immunostaining and flow cytometry.

Here, we present a protocol to perform an assay for transposase-accessible chromatin sequencing (ATAC-seq) on activated CD4+ human lymphocytes. The protocol has been modified to minimize contaminating mitochondrial DNA reads from 50% to 3% through the introduction of a new lysis buffer.
FAQs
Selectivity comes from antibodies recognizing the CD4 antigen on the target lymphocytes. When these antibodies are linked to magnetic beads or another capture surface, cells displaying CD4 can attach to the capture reagent, whereas cells lacking the recognized antigen remain unbound. This molecular recognition step determines which population becomes available for subsequent biological analysis.
The capture surface provides a physical handle for separating antigen-bound cells from the rest of the sample. Antibodies supply the recognition function, while the attached beads or surface retain the cells that have formed antigen-antibody complexes. This division of roles allows selective enrichment without relying only on the cells’ original distribution in the mixed sample.
Enrichment concentrates the CD4-positive population so investigators can examine it without treating the entire mixed sample as one indistinguishable group. The resulting preparation supports more focused phenotyping, molecular analysis, and functional assays. It also helps frame observations around CD4-positive lymphocytes when studying immune responses, disease-associated changes, or interactions between cell populations.
A typical workflow begins with a mixed biological sample and an antibody-based capture reagent directed toward CD4. The reagent is allowed to bind the target cells, after which washing removes cells and material that remain unbound. The retained, enriched cell fraction can then be made available for the selected downstream study, such as phenotyping or functional testing.
The enriched cells can be directed into several types of follow-up analysis. Phenotyping examines cellular characteristics, molecular analysis investigates relevant cellular molecules, and functional assays assess biological activity. Because capture concentrates the population of interest, these approaches can be applied specifically to CD4-positive lymphocytes rather than only to the original mixed sample.
This approach is useful when a study needs to focus on CD4-positive lymphocytes within a broader biological sample. Applications include investigating immune responses, examining disease-associated changes, and studying cellular interactions. Selective enrichment makes the target population more accessible for comparison and characterization, supporting research questions that depend on distinguishing these lymphocytes from other cells.
