microfibril noun[ C ] anatomy specializeduk /ˌmaɪ.krəʊˈfaɪ.brɪl/ us /ˌmaɪ.kroʊˈfaɪ.brəl/ a very thin, thread-like structure in a cell: microfibril bundleStudies have shown that individual microfibrils and microfibril bundles have elastic properties. These mutant proteins are thought to interfere with microfibril assembly. Microfibrils become part of the fibres that provide strength and flexibility to connective tissue. Decreased microfibril formation weakens the elastic fibres. Deposits of elastin first appear within microfibril bundles, then go on to form the central crosslinked elastin core of mature elastic fibres.
