Total Internal Reflection Fluorescence (TIRF) microscopy is a powerful approach to observe structures close to the cell surface at high contrast and temporal resolution. We demonstrate how TIRF can be employed to study protein dynamics at the cortex of cell wall-enclosed bacterial and fungal cells.

Herein we describe two approaches to characterize cell polarization events in B lymphocytes during the formation of an IS. The first, involves quantification of organelle recruitment and cytoskeleton rearrangements at the synaptic membrane. The second is a biochemical approach, to characterize changes in composition of the centrosome, which undergoes polarization to the immune synapse.

In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...
FAQs
Cytoskeletal activity provides an internal framework that can reorganize as neurons extend axons, change shape, and adjust synaptic connections. Its coordinated interaction with membrane behavior, organelle positioning, and signaling pathways helps direct where cellular growth or structural changes occur. In neuroscience, these dynamics are important for relating neuronal architecture to development, circuit function, and responses to injury.
Changes in the cell membrane help neurons interact with their surroundings and modify contacts with other cells, while organelle movement supports the redistribution of internal materials. These processes operate together rather than independently. Examining their timing and location can clarify how neurons maintain growth, transport materials, form connections, and adapt cellular organization during changing neural conditions.
Signaling pathways coordinate structural and organizational changes by linking environmental information to activity in the cytoskeleton, membrane, and organelles. This coordination allows a neuron to respond differently depending on the local cellular context, such as an extending axon or a synaptic site. Studying these links helps connect molecular signals with visible changes in neuronal behavior.
Live-cell analysis, imaging, and molecular labeling are complementary approaches for examining cellular changes as they occur. Imaging follows alterations in structure, movement, or organization, while molecular labeling helps associate those changes with particular cellular components or signals. Used together, these methods can connect dynamic behavior to neuronal growth, synaptic remodeling, transport, injury responses, or disease-related changes.
Tracking axon extension shows how neuronal processes develop and change, whereas monitoring synaptic remodeling reveals how connections are formed or adjusted. Examining both processes over time helps researchers relate cellular behavior to neural development and circuit function. These observations can also identify how neurons respond after injury and may inform investigations of therapeutic strategies.
In neuroscience, researchers can use dynamic measurements to compare neuronal behavior before and after injury or under disease-associated conditions. Changes in axon growth, material transport, cellular organization, or synaptic structure may reveal altered responses that are not apparent from a static image. This context supports studies linking cellular mechanisms with neural dysfunction and potential therapeutic approaches.
