Roles of isolectin B4-binding afferents in colorectal mechanical nociception.

La J, Feng B, Kaji K, Schwartz E, Gebhart G (2016) Roles of isolectin B4-binding afferents in colorectal mechanical nociception. Pain 157:348-354. doi: 10.1097/j.pain.0000000000000380

Summary: Primary afferent neurons are often classified as peptidergic or non-peptidergic. One characteristic of the non-peptidergic neurons is that they bind isolectin-B4. In the spinal cord these neurons terminate mainly in inner lamina II. Non-peptidergic neurons in the spinal cord have been found to be involved in various aspects of pain response. In this work the authors examined the role of non-peptidergic neurons in the viscerosensory system. Rats received 1.5 μg of intrathecal recombinant IB4-SAP (Cat. #IT-10) between the L5 and L6 vertebrae. Saporin (Cat. #PR-01) was used as a control. While IHC demonstrated that a majority of viscerosensory L6 colon DRG neurons are IB4+, they do not play a significant role in colorectal mechano-nociception.
