Mezzanismu
X'inhu verament l-assi bejn il-gut u l-moħħ
Sistema ta' komunikazzjoni reali, karatterizzata estensivament f'rodenti, u ħafna inqas stabbilita fil-poplu li qed jiġi mmarkat għalih.
Il-patways
| Triq | Mezzanismu | Evidenza f'bnedmin |
|---|---|---|
| Nervu vagus | Fibra afferenti tittrasporta sinjali mill-gut għall-bażi tal-moħħ | Stabbilit anatomicament; ir-rwol kaużali aktar diffiċli biex jiġi testat |
| Metaboli mikrobiċi | Aċidi grassi qosra u prekursorijiet ta' neurotransmitter jidħlu fil-kirkuazzjoni | Measurabbli; effetti downstream mhux ċari |
| Sinjalizzazzjoni immuni | Permeabilità tal-gut u cytokines infjammatorji | Assoċjazzjonijiet stabbiliti; direzzjoni kontestata |
| Assi HPA | Hormoni ta' stress jibdlu l-funzjoni tal-gut u l-invers | Bidirezzjonali u dokumentati tajjeb |
| Sistema nervu enterika | Neuroni intrinsiċi tal-gut li jaħdmu semi-indipendentement | Karatterizzati tajjeb |
Ebda minn dan mhuwiex fringe. Is-sistema nervu enterika fiha mijiet ta' miljun neuroni u taħdem b'autonomija sostanzjali. L-istat tal-gut jaffettwa l-umor u l-umor jaffettwa l-funzjoni tal-gut, kif kull min kien nervuż qabel eżami diġà jaf.
Patways ta' komunikazzjoni bejn il-gut u l-moħħ
Il-problema tad-direzzjoni
Rivista sistematika ssib differenzi fil-mikrobiota bejn in-nies b'depressjoni jew ansjetà u kontrolli [2]. Il-mistoqsija li tiddeċidi kollox hi liema direzzjoni tgħaddi l-arloġġ.
Id-depressjoni tbiddel x'jiekol in-nies, kemm jimmovimentaw, kif jorqod u spiss x'ħin ta' mediċina jieħdu. Kull waħda minn dawk tbiddel il-mikrobioma. Differenza fil-kompożizzjoni mikrobiċi hija għalhekk eżattament dak li tistenna jekk id-depressjoni tikkawża bidla fil-mikrobioma u l-mikrobioma ma jagħmel xejn.
L-istess diffikultà tapplika għall-letteratura tas-sindromu metaboliku [3] u għall-ħidma tal-awtiżmu [4], fejn is-selettività dietetika hija komuni u tipproduċi differenzi fil-mikrobioma waħedha.
X'jista' jsolvi dan
Provi randomizzati ta' interventi definiti tal-mikrobioma b'endpoint kliniku, durazzjoni adegwata u daqs ta' kampjun adegwat. Dawn qed jibdew jidhru u huma r-raġuni għaliex din il-paġna se tinbidel. Sa dak il-punt, il-pożizzjoni onesta hi li l-assi jeżisti u l-applikazzjonijiet tal-konsumatur mibnija fuqha huma mhux provati — ara probiotiċi.
Mistoqsijiet komuni
L-imsaren huma verament "it-tieni moħħ"?
90% tas-serotonina tiġi mill-imsaren?
Il-bidla fid-dieta tiegħi tista' tibdel il-burdata tiegħi permezz tal-imsaren?
X'għandi verament nagħmel?
