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.

Studying Lymphocyte Transmigration Across a Microvascular Endothelial Cell Monolayer

2025
This video demonstrates an experimental investigation of lymphocyte transmigration across a blood-brain barrier (BBB) endothelium model. A monolayer of human brain microvascular endothelial cells (HBMECs) is generated in vitro, and peripheral blood mononuclear cells (PBMCs) containing lymphocytes are added to the monolayer. The cells are then incubated to allow lymphocyte transmigration, and the migrated cells are quantified using flow cytometry.

This video demonstrates a monocyte-derived dendritic cell, MoDC-based assay to measure the immunogenicity of commercially available vaccines. MoDC assays investigate dendritic cell responses to antigens, pathogens, or treatments and can provide insights into immune responses, vaccine development, and immunotherapy research.
FAQs
Recognition depends on a matching interaction between a T-cell receptor and a peptide antigen displayed by a major histocompatibility complex molecule. This arrangement allows T lymphocyte cells to respond to particular threats rather than activating indiscriminately. The presentation step therefore provides molecular specificity to adaptive immunity and helps determine which T-cell responses become engaged.
CD4+ T cells primarily help activate other immune cells, coordinating the broader response after antigen recognition. CD8+ T cells can destroy infected or abnormal cells, providing a direct removal mechanism. This division of activity gives adaptive immunity both an organizing function and an effector function, allowing responses to combine immune coordination with targeted cellular elimination.
Activation initiates a response to recognized antigen, while differentiation produces T-cell populations with specialized functions. Some responding cells also form memory, shaping how the immune system reacts over the long term. Together, these processes influence the strength, specialization, and persistence of immunity, making them important for understanding both protection and dysregulated immune responses.
During infection, these cells can coordinate immune activity or eliminate infected cells after recognizing presented peptide antigens. Vaccination is relevant because it aims to shape lasting adaptive immunity, including T-cell memory. Studying activation, differentiation, and memory formation helps researchers examine how immune protection is established and why its effects can persist beyond the initial exposure.
T-cell activity can influence immune regulation beyond defense against infection. When responses are improperly directed or controlled, they are relevant to autoimmunity, whereas recognition and immune regulation also affect transplant outcomes. Examining T-cell activation and coordination therefore helps researchers connect cellular immune mechanisms with conditions in which the immune response harms tissues or challenges transplanted material.
Cancer immunotherapy research can redirect T cells toward malignant targets, using their capacity for targeted cellular responses against abnormal cells. This approach builds on the distinction between recognizing a relevant antigen and carrying out an effector response. Studying T-cell specificity, activation, and function helps investigators evaluate strategies intended to improve immune attack against cancer.
