Celule enteroendocrine

G (gastrina)- efecte stimulatoare multiple (secretorii, moto- 

rii, trofice) 

( APUD – Amine Precursor Uptake and Decarboxilation )

D (somatostatina) – inhib ă secreţia gastrinei, inhibă

motilitatea stomacului 

S (secretina) – inhibă motilitatea stomacului,

stimulează secreţia pancreasului, stimulează secreţia bilei, inhibă secreţia HCl, stimulează 

secreţia pepsinei 

EC (serotonina şi endorfina)- stimuleaz ă secreţia şi mo - 

tilitatea 

I (cholecistokinina) – inhibă secreţia şi motilitatea 

stomacului

K ( peptida gastrică inhibitoare)-inhibă secreţia HCL 

A(enteroglucagon) – stimulează metabolismul glicogenului 

D1 (VIP-peptida vasoactivă) – dilată vasele, scade PA

ECL

( histamina )  

stimuleaz ă secreţia celulelor parietale
