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.

FAQs
Cytoskeletal changes provide the structural basis for extending and reorganizing dendritic branches. As this internal framework changes, growing dendrites can develop more elaborate branching patterns and support the formation of dendritic spines. These structural adjustments influence how many potential contacts a neuron can receive, helping developing neural circuits establish and refine their connectivity.
Neuronal activity and molecular signals help determine which developing connections persist and which are eliminated. This selective process prevents every emerging contact from becoming permanent and allows neural circuits to adjust their organization. Consequently, dendrite growth is not simply an accumulation of branches or spines; it includes experience-sensitive refinement of potentially functional connections.
Dendritic branching changes the larger-scale architecture of a neuron, whereas dendritic spines are smaller structures associated with individual receiving sites. Both can be shaped during development and learning, but they represent different levels of remodeling. Considering them separately helps researchers distinguish changes in overall neuronal structure from changes in the specific contacts that may support synaptic plasticity.
Changes in dendritic structure can alter how neurons receive and integrate signals, linking cellular remodeling with synaptic plasticity. Because learning involves experience-related changes in neural circuits, dendrite growth provides a structural perspective on how those circuits may be modified. Studying these changes therefore helps connect psychological processes such as memory formation with adaptations occurring in the nervous system.
Research on dendrite growth can show how experience is associated with the development, stabilization, or removal of neuronal connections. This perspective helps explain why neural circuits remain adaptable rather than fixed. In psychology and neuroscience, the findings provide a cellular context for examining how learning and other experiences may influence circuit organization and the capacity for synaptic change.
Abnormal neuronal development can disrupt the structural changes needed to establish or refine neural connections, potentially contributing to cognitive impairment and neurodevelopmental conditions. Dendrite growth is also relevant after brain injury because remodeling may participate in circuit changes associated with recovery. Examining these processes can therefore link cellular development with both dysfunction and possible restoration of neural connectivity.
