p75NTR Antibody

About the Target

The p75NTR (p75 neurotrophin receptor, also known as TNFRSF16) is an unconventional member of the tumor necrosis factor receptor superfamily, originally defined as a neurotrophin receptor that binds soluble, dimeric neurotrophins such as NGF, BDNF, NT-3, and NT-4, as well as their proneurotrophin precursors. Structurally, it consists of an extracellular region with four cysteine-rich domains (CRDs) stabilized by disulfide bonds, a single 21-amino acid transmembrane segment, and an intracellular portion containing a juxtamembrane region, a Chopper domain important for apoptosis, and a C-terminal death domain that, unlike canonical TNFR death domains, does not self-associate. p75NTR. Depending on the literature source, P75NTR may also be discussed as Tumor necrosis factor receptor superfamily member 16 and Gp80-LNGFR.

Reported cellular context includes cell membrane, cell projection, cytoplasm, and membrane, which can matter when signal is compared across treatments or changing cell states. Following P75NTR across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

P75NTR is commonly interpreted in the context of immunology, neuroscience, and inflammation research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane, cell projection, and cytoplasm, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between cell membrane, cell projection, and cytoplasm across matched conditions
• context differences tied to immune-cell state, activation, or lineage composition
• compartment-specific patterns relevant to neuronal polarity, transport, or synaptic context
• responses associated with cytokine exposure, inflammatory tone, or tissue stress

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for P75NTR. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in P75NTR reflect biology rather than handling. When interpreting P75NTR, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep P75NTR trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
