일반 설명
Pertussis (Pertussis) toxin (PTX) is a protein isolated from the bacterium Bordatella (Bordatella) coccobaccillus. The toxin is excreted in a non-active state. When the B oligomer of the bacterium, Bordatella coccobacillus, comes in contact with the cell membrane, an S1 subunit of its A protomer is activated. This activation may be mediated by glutathione and/or ATP.
애플리케이션
Pertussis toxin from Bordetella pertussis has been used: to enhance cardiac myosin immunization of rats to induce myocarditis; to break down the blood–brain barrier in the Cuprizone and cuprizone/MOG-EAE model; as an inhibitor of Gαi signaling
The toxin is released from B. pertussis in an inactive form. When the pertussis toxin B oligomer binds to the cell membrane, the S1 subunit of its A protomer becomes activated, perhaps through the action of glutathione and ATP. A protocol for activating pertussis toxin in vitro is given by Kaslow, et al.
생화학적/생리학적 작용
Pertussis toxin catalyzes the ADP-ribosylation of the α subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt. This prevents the G protein heterotrimers from interacting with receptors, thus blocking their coupling and activation. Since the Gα subunits remain in their GDP-bound, inactive state, they are unable to inactivate adenylyl cyclase or open K+ channels.

G-protein receptor kinases (GRKs) regulate adult hearts by modulating inotropic, chronotropic and hypertrophic signaling of 7-transmembrane spanning neurohormone receptors. GRK-mediated desensitization and downregulation of β-adrenergic receptors has been implicated in adult heart failure; GRKs are therefore a promising therapeutic target.

FTY720, a sphingosine 1-phosphate (S1P) receptor modulator, suppresses immune responses by inhibiting T-cell migration into target tissues; however, it does not alter T-cell functions. In this study, we investigated the biological effects of FTY720 on NKT cells. Unlike T cells

Increasing evidence has suggested that a single nucleotide polymorphism in the Ncf1 gene is associated with experimental autoimmune encephalomyelitis (EAE). However, the mechanisms of NCF1-induced immunoregulatory effects remain poorly understood. In this study, we focus on NCF1 deficiency-mediated effects on

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
