Inhibition of bombesin-induced mitogenesis by pertussis toxin : Dissociation from phospholipase C pathway [PDF]
, 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

mBio, 2019 Monocytes arriving at the site of infection differentiate into functional effector macrophages to replenish the resident sentinel cells. Bordetella pertussis, the pertussis agent, secretes an adenylate cyclase toxin-hemolysin (CyaA) that binds myeloid ...

PLoS ONE, 2011 Pertussis (whooping cough) is frequently complicated by concomitant infections with respiratory viruses. Here we report the effect of Bordetella pertussis infection on subsequent influenza virus (PR8) infection in mouse models and the role of pertussis ...

Effect of pertussis toxin on α2-adrenoceptors: decreased formation of the high-affinity state for agonists [PDF]
, 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.

Inhibition of endothelin-mediated topoisomerase I activation by pertussis toxin [PDF]
, 1990 Cultured rat mesangial cells contain high affinity endothelin (ET) receptors at high densities. Exposure of these cells to ET resulted in a transient activation of topoisomerase I extractable activity, which reached its maximum value at approximately 2 ...

Experimental Biology and Medicine, 1933 Mishulow, Mowry and Scott1 demonstrated that exotoxic filtrates could be obtained from whooping cough cultures. They planted their organisms on chocolate agar over which they had poured a small amount of horse serum-beef heart broth. The small amount of diluent made the harvest of toxin necessarily small. On the other hand, Craster and Smith2 mentioned

Hydrophobic photolabelling of pertussis toxin subunits interacting with lipids [PDF]
, 1986 The hydrophobic surfaces presumably involved in the membrane interaction of pertussis toxin have been mapped by a new detergent-binding assay. This is based on the interdispersion among detergent micelles of trace amounts of radioactive photoreactive ...

Pertussis toxin treatment increases glutamate release and dihydropyridine binding sites in cultured rat cerebellar granule neurons [PDF]
, 1993 : This study was designed to examine the ability of pertussis toxin to block various responses due to (-)-baclofen in cultured cerebellar granule neurons of the rat.

Prevention of pertussis: An unresolved problem
Human Vaccines & Immunotherapeutics, 2018 Pertussis is a highly contagious respiratory disease caused by Bordetella pertussis. However, after the introduction of the whole-cell pertussis vaccine (wP), the annual incidence rates of the disease progressively declined.

The Turkish Journal of Pediatrics, 2009 This prospective study, which was designed to compare nasopharyngeal culture, polymerase chain reaction (PCR) and serology in the diagnosis of pertussis, covered 35 children aged between 0 and 16 who were admitted to Hacettepe University Ihsan ...
