Research Findings

Elaunin fibers have been found within the secretory coil of human eccrine sweat glands. They were in found in bundles of microtubules which had a different constancy than elastic fibers. The elaunin fibers found in the secretory coil had a less thicker appearance than that of elastic fibers. Elaunin can be identified where the fibers of gingival ligament. There are elastic fibers and one of the main type of elastic fiber is elaunin In the papillary dermis elaunin is lost when in reduction.
