The aroylhydrazone INHHQ prevents memory impairment induced by Alzheimer's-linked amyloid-β oligomers in mice.
De Falco A, Kincheski GC, Atrián-Blasco E, Hureau C, Ferreira ST, Rey NA. De Falco A, et al. Among authors: ferreira st. Behav Pharmacol. 2020 Dec;31(8):738-747. doi: 10.1097/FBP.0000000000000578. Behav Pharmacol. 2020. PMID: 32773452
Systemic administration of a single dose of INHHQ (1 mg/kg) prevented both short-term and long-term memory impairment caused by AbetaOs in mice. In-vitro studies showed that INHHQ prevents Cu(Abeta)-catalyzed production of reactive oxygen species. ...

Quercetin reduces neutrophil recruitment induced by CXCL8, LTB4, and fMLP: inhibition of actin polymerization.
Souto FO, Zarpelon AC, Staurengo-Ferrari L, Fattori V, Casagrande R, Fonseca MJ, Cunha TM, Ferreira SH, Cunha FQ, Verri WA Jr. Souto FO, et al. Among authors: ferreira sh. J Nat Prod. 2011 Feb 25;74(2):113-8. doi: 10.1021/np1003017. Epub 2011 Jan 28. J Nat Prod. 2011. PMID: 21275387
Recent in vitro data have suggested that the flavonoid quercetin (1) does not affect the functioning of neutrophils. Therefore, we evaluated in vivo and in vitro whether or not 1 affects neutrophil function, focusing on recruitment. ...

Protein kinase C activity regulates D-serine availability in the brain.
Vargas-Lopes C, Madeira C, Kahn SA, Albino do Couto I, Bado P, Houzel JC, De Miranda J, de Freitas MS, Ferreira ST, Panizzutti R. Vargas-Lopes C, et al. Among authors: ferreira st. J Neurochem. 2011 Jan;116(2):281-90. doi: 10.1111/j.1471-4159.2010.07102.x. J Neurochem. 2011. PMID: 21070240 Free article.
Here, we investigated whether PKC activity regulates SR activity and D-serine availability in the brain. In vitro, PKC phosphorylated SR and decreased its activity. PKC activation increased SR phosphorylation in serine residues and reduced D-serine levels in astrocyte and …

Fractalkine mediates inflammatory pain through activation of satellite glial cells.
Souza GR, Talbot J, Lotufo CM, Cunha FQ, Cunha TM, Ferreira SH. Souza GR, et al. Among authors: ferreira sh. Proc Natl Acad Sci U S A. 2013 Jul 2;110(27):11193-8. doi: 10.1073/pnas.1307445110. Epub 2013 Jun 17. Proc Natl Acad Sci U S A. 2013. PMID: 23776243 Free PMC article.
Fractalkine's hypernociceptive effect appears to be indirect, as it was reduced by local treatment with anti-TNF-alpha antibody, IL-1-receptor antagonist, or indomethacin. Accordingly, the in vitro incubation of isolated and cultured SGC with fractalkine induced the produc …
