Alpha-synuclein (αSyn) and beta-synuclein (βSyn) are small, soluble proteins belonging to the synuclein family, primarily expressed in neurons. αSyn is extensively studied due to its central role in neurodegenerative disorders, particularly Parkinson’s disease (PD) and other synucleinopathies, where it forms pathological aggregates in Lewy bodies. In contrast, βSyn shares structural homology with αSyn but exhibits distinct biochemical properties, potentially inhibiting αSyn aggregation and modulating its toxicity. Antibodies targeting αSyn and βSyn are critical tools for investigating their physiological functions, pathological roles, and interactions.

αSyn-specific antibodies are widely used in research and diagnostics to detect pathological forms (e.g., oligomers, phosphorylated species) in brain tissues, biofluids, or experimental models. They aid in elucidating mechanisms of neurodegeneration and evaluating therapeutic strategies. βSyn antibodies, though less studied, help explore its neuroprotective roles and regulatory interplay with αSyn. Both monoclonal and polyclonal antibodies are developed, often validated via techniques like immunohistochemistry, Western blot, and ELISA.

Challenges include ensuring specificity due to sequence similarities among synuclein family members (α, β, γ) and distinguishing between normal and disease-associated conformations. Recent advances in epitope mapping and conformation-sensitive antibody design enhance diagnostic accuracy. These antibodies also hold potential as biomarkers in cerebrospinal fluid or blood for early disease detection. Continued refinement of synuclein-targeting antibodies remains vital for understanding synuclein biology and advancing therapies for neurodegenerative diseases.
