INTRATHECAL PERTUSSIS TOXIN INDUCES THERMAL HYPERALGESIA: INVOLVEMENT OF EXCITATORY AND INHIBITORY AMINO ACIDS

open access: yes, 2020
-Intrathecal pertussis toxin injection has been used as a neuropathic pain model. In the present study, its effects on cerebrospinal fluid biochemistry and nociceptive behavioral expression were examined in rats.

Purification design and practice for pertactin, the third component of acellular pertussis vaccine, from Bordetella pertussis

open access: yes, 2016
Development of acellular pertussis vaccine (aPV) requires purification of several components from Bordetella pertussis. While the components pertussis toxin (PT) and filamentous hemagglutinin (FHA) have been successfully purified, the third component ...

Effect of pertussis toxin on islet insulin secretion in obese (fa/fa) Zucker rats

open access: yes
We used isolated islets of lean and obese Zucker rats to determine whether inhibitory pathways mediated by pertussis toxin-sensitive guanyl nucleotide-binding (Gi) proteins contribute to hyperinsulinemia in obese rats.

Inhibition of bombesin-induced mitogenesis by pertussis toxin : Dissociation from phospholipase C pathway

open access: yes, 1987
Prior incubation of quiescent cultures of Swiss 3T3 cells with pertussis toxin selectively inhibited the stimulation of DNA synthesis induced by peptides of the bombesin family. While pertussis toxin blocked mitogenesis at an early stage in the action of

Effect of pertussis toxin on α2-adrenoceptors: decreased formation of the high-affinity state for agonists

open access: yes, 1984
Administration of pertussis toxin to hamsters abolishes the α2-adrenergic inhibition of adenylate cyclase in their adipocytes. The toxin did not modify the number of adipocyte α2-adrenoceptors or their affinity for antagonists.
