Application
JNJ7777120 has been used as a histamine-4 receptor antagonist:
- to study its effects on the pro-inflammatory microglia in rats
- to study its effects on the Parkinson′s-like pathology in rat brain
- to study its effects on the histamine receptor interaction in periodontal ligament fibroblasts (PDLF)
Biochem/physiol Actions
JNJ7777120 may exhibit neuroprotective effects against ischemic brain damage. It acts as an anti-inflammatory agent to treat inflammatory diseases. JNJ7777120 is observed to reduce colonic injury, cytokine production, and neutrophil infiltration.
JNJ7777120 is a potent, selective non-imidazole H4 histamine receptor antagonist.

Natural killer (NK) cells have been detected in the lesional skin of patients with inflammatory skin diseases, where high levels of histamine are also present. Therefore, we investigated the effect of histamine, in particular via the histamine H4 receptor (H4R)

Growing evidence indicates that microglia activation and a neuroinflammatory trigger contribute to dopaminergic cell loss in Parkinson's disease (PD). Furthermore, increased density of histaminergic fibers and enhanced histamine levels have been observed in the substantia nigra of PD-postmortem brains. Histamine-induced
