Substance P- and calcitonin gene-related peptide-like immunoreactive pericellular baskets in human trigeminal ganglion.
Presence of pericellular basket-like network of fibres immunoreactive to substance P and to calcitonin gene-related peptide is shown around non-immunoreactive primary sensory neurons of human trigeminal ganglion. Single neurons can be wrapped by either peptide-containing fibres or by both. Such pericellular structures might represent sites of interneuronal communications at ganglionic level.
