Substance P-Saporin (SP-SAP) is under development as a chronic pain therapeutic with tremendous potential to permanently eliminate suffering in many painful diseases and conditions. ATS is awaiting news from the National Institutes of Health on further funding to fulfill FDA requirements to bring SP-SAP to clinical trial in humans. ATS has a patent on SP-SAP […]

Dopaminergic neurons are widely studied because of their role in one of the devastating diseases of old age, Parkinson’s. Lesioning studies using 6-hydroxydopamine or MPTP have been useful in research on Parkinson’s Disease. However, these reagents have limitations such as MPTP affecting catecholaminergic neurons and 6-OHDA stability and specificity issues. Targeting dopaminergic neurons with an

Neuroscience 119(1):223-232. doi: 10.1016/s0306-4522(03)00125-8 Summary: Administration of SP-SAP (Cat. #IT-07) eliminates sensitization of nocifensive reflexes. The authors investigate whether SP-SAP elimination of neurokinin-1 receptor-expressing neurons in the lumbar spinal cord affects nociceptive sensitivity in general, or preferentially affects
