Studies of neuronal morphogenesis using Drosophila larval dendritic arborization (da) neurons benefit from in situ visualization of neuronal and epidermal proteins by immunofluorescence. We describe a procedure that improves immunofluorescence analysis of da neurons and surrounding epidermal cells by removing muscle tissue from the larval body wall.

The neuronal membrane proteasome (NMP) was recently identified in a subset of somatosensory neurons as a key regulator of touch, pain, and itch perception. This article presents a robust workflow for analyzing cell-type-specific NMP expression and function using cell sorting, transcriptome profiling, and culture-based immunofluorescent analyses.

The cellular heterogeneity of brain tissue poses a significant limitation for the study of epigenetic markings in chromatin because most assays lack single cell resolution. Neurons typically are intermingled with glia and other non-neuronal cells. We provide a protocol to extract and collect neuronal nuclei from human brain.

Here we present a Fluorescence Activated Cell Sorting (FACS) protocol to study molecular alterations in Fos-expressing neuronal ensembles from both fresh and frozen brain tissue. The use of frozen tissue allows FACS isolation of many brain areas over multiple sessions to maximize the use of valuable animal subjects.
FAQs
Fixation and sectioning establish the physical basis for comparing tissue features. Fixation is performed before the sample is cut into sections, and the resulting sections can then be stained or exposed to marker-specific antibodies. This sequence makes cellular structure, marker distribution, and protein expression available for microscopic examination, providing a consistent starting point for downstream image analysis.
Stains and antibodies answer related but different analytical questions. Staining can reveal cells and their structural features, whereas antibodies bind selected neuronal or glial markers to identify particular cell types or molecular features. Choosing between these readouts, or combining them, determines whether analysis emphasizes general tissue organization, marker distribution, or protein expression.
Image analysis converts microscopic observations into measurable features such as morphology, distribution, connectivity, and protein expression. Morphology describes cellular form, while distribution and connectivity capture where cells or structures occur and how they relate. These quantitative readouts help compare neural organization across samples rather than relying only on descriptive visual inspection.
Standardization matters because tissue measurements must be comparable across experimental models and patient tissues. Consistent preparation and analysis reduce avoidable differences in observed cellular composition, structure, marker distribution, or protein expression. This improves interpretation when investigators evaluate developmental changes, injury responses, neurodegenerative pathology, or the effects of a treatment.
An analysis workflow generally proceeds from brain or spinal cord sampling to fixation, sectioning, labeling, microscopy, and image analysis. Labeling may use stains or antibodies directed at neuronal and glial markers. The final measurements can be organized around morphology, distribution, connectivity, or protein expression, depending on the biological question.
When researchers need to assess developmental changes, injury responses, neurodegenerative pathology, or treatment effects, neuronal tissue analysis provides tissue-level evidence. Comparing cellular and molecular measurements across conditions can show whether neural organization or marker expression changes with disease, damage, development, or intervention. Its value lies in connecting observed tissue changes to experimental questions in neuroscience.
In neuroscience, these analyses help connect neural organization with behavior and disease by relating tissue measurements to broader biological outcomes. Examination of patient tissues and experimental models can reveal shared or differing patterns in cellular composition, structure, and molecular features. Such comparisons support interpretation of how tissue-level alterations correspond to pathological or functional states.
