“…However, the following characteristics of the receptor are speculated to be responsible for its anti-inflammatory function: the homomeric α7 nicotinic receptor desensitizes very rapidly, compared with other heteromeric receptors, with its agonists [ 79 , 86 ]. Furthermore, the α7 nicotinic receptor activates the JAK2/STAT3 pathway [ 87 , 88 ] as well as the Akt pathway [ 89 , 90 ], the former suppressing NF-κB translocation into the nucleus and the latter activating the Nrf2 pathway [ 90 ], which upregulates antioxidative factor HO-1 [ 91 ]. Based on these, its short opening time, rapid desensitization, activation of cellular protecting signals, or suppression of NF-κB nuclear translocation may be responsible for anti-inflammatory effects [ 86 ].…”

“…Despite GLP-1 agonists and PPARγ agonists being primarily anti-diabetic drugs, recent findings indicate that these molecules execute neuroprotective and anti-inflammatory functions, which alleviate symptoms of AD and PD as well as rescuing Akt-1 and m-TOR, and insulin signaling in the brain (79)(80)(81)(82)(83)(84).…”

“…Badania takie prowadzone były najczęściej na modelach komórek odzwierciedlających komórki nerwowe, astrocytach lub neuronach (w badaniach in vitro) lub na modelach mysich i szczurzych. Badania te wskazały, że genisteina hamuje śmierć komórek wywołaną iniekcją krótkich odcinków β-amyloidu, najczęściej β-amyloidu(25-35) w komórkach PC12 [40][41][42][43], neuronach hipokampu [44][45][46] lub komórkach neuroblastomy SH-SY5Y [47][48][49][50]. W obserwowany efekt zaangażowanych może być wiele szlaków sygnalizacyjnych zależnych od kinazy JNK [42,43], kinazy białkowej C (ang.…”

“…W obserwowany efekt zaangażowanych może być wiele szlaków sygnalizacyjnych zależnych od kinazy JNK [42,43], kinazy białkowej C (ang. PKC) [41], kinazy Akt [49,46], erytroidowego czynnika jądrowego 2 (NRF2) [50], a także od zmian właściwości elektrofizjologicznych kanałów jonowych [45]. Ponadto, w wielu z tych badań odnotowano obniżenie poziomu ekspresji genów kodujących kaspazy i zahamowanie ich aktywności, głównie kaspazy 3 i 8, pod wpływem tego flawonoidu [42,44].…”
