How can you use “nka” in a sentence? Here are some example sentences to help you improve your vocabulary:
Thus, the antibody used, in the present work, principally recognizes NKA but shows some cross-reactivity with NKB.
It is also known that the biological actions of NKA, NKB and SP are mediated by three receptors, named neurokinin (NK)-1, NK-2 and NK-3 [ 2 ] . Thus, the tachykinins have been implicated in several physiological actions such as salivation, the regulation of smooth muscle contraction, depolarization of central neurons, hyperactivity, interaction with dopaminergic A-10 neurons mediating behavioral activation, regulation of blood pressure, and the transmission of the baroreceptor reflex [ 3 4 5 6 7 ] . In addition, a loss of tachykinin-containing neurons has been described in neurodegenerative diseases [ 8 ] , suggesting that the decrease in the amount of tachykinins could be involved in these and other diseases [ 9 10 ] .
Moreover, in the midbrain of the rat those authors described NKA in the substantia nigra, the interpeduncular nucleus and the periaqueductal gray [ 29 ] , just as we found NK-ir structures in these nuclei of the human brainstem when using immunocytochemical techniques.
As is known, this latter tachykinin derives from the pre-protachykinin B gene, whereas SP and NKA derive from another precursor, the pre-protachykinin A gene.
Thus, the anti-NKB antibody (IHC 7357) showed the following crossreactivities: 100% for NKB, 2% for physalaemin, 1% for eledoisin, 0.6% for kassinin, 0.2% for substance P, 0.1% for NKA and 0% for neuropeptide K. Moreover, in the nuclei of the human brainstem in which NKB was observed, the density of the immunoreactivity for NKB was lesser than that found in the same nuclei for NKA (see and compare Figs.
