▎ Glutathione yog dab tsi?
Glutathione, uas yog, GSH, yog ib qho tripeptide uas muaj glutamic acid, cysteine, thiab glycine, thiab nws cov qauv qauv yog γ-L-glutamyl-L-cysteineylglycine. Nws muaj cov haujlwm tseem ceeb physiological hauv cov kab mob nyob. Raws li ib qho tseem ceeb uas tsis yog-protein thiol compound nyob rau hauv cov hlwb, nws muaj ntau yam kev ua haujlwm xws li tshuaj tiv thaiv oxidation, detoxification, thiab kev koom tes hauv kev tswj hwm ntawm cellular metabolism, ua lub luag haujlwm tseem ceeb hauv kev tswj cov kev ua haujlwm ntawm cov hlwb thiab kev ruaj ntseg ntawm ib puag ncig sab hauv.
▎ Glutathione Kev Tshawb Fawb
Kev tshawb fawb keeb kwm ntawm Glutathione yog dab tsi?
Kev tshawb pom thiab kev txiav txim siab ntawm glutathione: Xyoo 1888, glutathione tau pom thawj zaug hauv cov poov xab. Xyoo 1921, cov kws tshawb fawb tau txiav txim siab ntxiv nws cov qauv tshuaj. Nws yog tripeptide tsim los ntawm condensation ntawm glutamic acid, cysteine, thiab glycine los ntawm peptide bonds.
Kev lees paub txog nws lub luag haujlwm tseem ceeb hauv cov kab mob muaj sia: Txij li xyoo 1930s, tib neeg tau maj mam lees paub tias glutathione muaj ntau yam haujlwm tseem ceeb hauv cov kab mob muaj sia. Nws koom nrog hauv cov tshuaj tiv thaiv redox hauv cov hlwb, ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev ruaj ntseg ntawm ib puag ncig intracellular thiab tiv thaiv cov hlwb los ntawm kev puas tsuaj oxidative. Nyob rau tib lub sijhawm, nws tseem ua lub luag haujlwm tseem ceeb hauv cov txheej txheem physiological xws li kev thauj mus los ntawm cov amino acid thiab kev tswj hwm ntawm enzyme kev ua haujlwm. Cov kev tshawb pom no tau tso lub hauv paus theoretical rau kev siv glutathione hauv kev kho mob.
Kev tshawb fawb txog cov peev txheej uas tau tsav los ntawm daim ntawv thov kev kho mob xav tau: Nrog rau kev tshawb fawb tob zuj zus ntawm kev ua haujlwm ntawm lub cev ntawm glutathione, nws cov peev txheej hauv kev kho mob tau dhau los ua qhov tseem ceeb. Nws yog siv los kho ntau yam kab mob, xws li kab mob siab thiab kab mob qhov muag, thiab tseem tuaj yeem siv los ua cov tshuaj antioxidant. Txhawm rau ua kom tau raws li qhov xav tau loj rau glutathione hauv kev siv tshuaj kho mob, cov kws tshawb fawb tau pib mob siab rau lawv tus kheej los tshawb nrhiav cov txiaj ntsig zoo thiab ruaj khov ntawm glutathione, uas tau txhawb nqa kev tshawb fawb tob ntawm nws qhov chaw.
Dab tsi yog qhov mechanism ntawm kev txiav txim ntawm Glutathione?
1. Antioxidant nyhuv
Glutathione (GSH) yog ib qho antioxidant zoo uas koom nrog hauv kev tiv thaiv antioxidant hauv cov hlwb. Nws tuaj yeem cuam tshuam ncaj qha nrog cov pa oxygen reactive (ROS) xws li hydrogen peroxide (H₂O₂) thiab txo lawv mus rau cov khoom tsis zoo (Reddy V N. 1990; Sinha R, 2018). Piv txwv li, los ntawm glutathione redox voj voog, glutathione reacts nrog H₂O₂ thiab hloov mus rau hauv dej, yog li tiv thaiv cov hlwb los ntawm oxidative puas. Hauv cov txheej txheem no, glutathione yog oxidized rau oxidized glutathione (GSSG), tab sis glutathione reductase hauv cell tuaj yeem txo GSSG rov qab mus rau GSH, tswj lub peev xwm antioxidant ntawm tes.
Glutathione tseem tuaj yeem tiv thaiv -SH pawg ntawm cov cell membrane, uas ua lub luag haujlwm tseem ceeb hauv cation thauj thiab membrane permeability. Los ntawm kev tswj xyuas qhov txo qis hauv lub xeev ntawm daim nyias nyias -SH pawg, glutathione pab tswj kev ruaj ntseg thiab kev ua haujlwm ntawm cov cell membrane [1].
2. Cov nyhuv detoxification
Glutathione plays lub luag haujlwm tseem ceeb hauv cov txheej txheem detoxification. Nws tuaj yeem khi rau cov co toxins los tsim cov tshuaj tsis muaj tshuaj lom lossis tsis muaj tshuaj lom thiab txhawb nqa lawv tawm ntawm lub cev. Piv txwv li, nyob rau hauv daim siab, glutathione khi rau ntau yam teeb meem tshuaj thiab raug tawm los ntawm lub cev los ntawm cov kua tsib los yog zis, tiv thaiv daim siab hlwb los ntawm kev puas tsuaj ntawm co toxins. Lub siab yog lub ntsiab detoxification ntawm tib neeg lub cev, thiab lub luag hauj lwm ntawm glutathione nyob rau hauv nws yog ib qho tseem ceeb heev.
3. Ua rau lub cev tiv thaiv kab mob
Glutathione muaj cov haujlwm tseem ceeb hauv lub cev tiv thaiv kab mob. Nyob rau hauv macrophages, ntuj killer hlwb, thiab T hlwb, piv txwv li, nws muaj peev xwm tswj cell activation, metabolism, tsim nyog cytokine tso, redox kev ua, thiab dawb radical qib [2] . Lub cev tiv thaiv kab mob ua lub luag haujlwm tseem ceeb hauv kev tawm tsam cov kab mob thiab tswj kev noj qab haus huv ntawm lub cev. Glutathione txhim kho lub cev tiv thaiv kab mob los ntawm kev tswj cov haujlwm ntawm cov hlwb no.
Glutathione tuaj yeem txhim kho kev ua haujlwm redox, hloov cytokine profile ntawm Th1-hom lus teb, thiab txhim khu kev ua haujlwm ntawm T lymphocytes, yog li ua si lub luag haujlwm tseem ceeb hauv immunomodulatory thiab antioxidant [2] . Th1-type cytokines feem ntau koom nrog hauv kev tiv thaiv kab mob hauv lub cev tiv thaiv kab mob xws li kab mob, kab mob, thiab qog hlwb. Glutathione txhim kho lub cev tiv thaiv kab mob los ntawm kev tswj hwm qhov sib npaug ntawm cytokines.
4. Lub luag haujlwm hauv kev ua me nyuam
Glutathione plays lub luag haujlwm tseem ceeb hauv cov txiv neej thiab poj niam cov kab mob ntawm cov tsiaj nyeg thiab nyob rau theem pib ntawm kev loj hlob ntawm embryonic. Hauv txiv neej thiab poj niam gametes, GSH koom nrog kev tiv thaiv cov hlwb los ntawm kev puas tsuaj oxidative [3] . Piv txwv li, thaum lub sij hawm spermatogenesis, qhov concentration ntawm glutathione maj mam txo, thiab thaum lub sij hawm oocyte maturation, lub synthesis ntawm glutathione yog tswj los ntawm gonadotropins, thiab nws cov concentration kuj hloov. Glutathione kuj tseem muaj feem xyuam rau kev tswj cov morphology ntawm meiotic spindle ntawm oocyte. Tom qab fertilization, nws plays lub luag hauj lwm zoo nyob rau hauv tsim ntawm tus txiv neej pronucleus thiab kev loj hlob ntawm lub embryo thaum ntxov mus rau lub blastocyst theem. Tsis tas li ntawd, cumulus hlwb kuj ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm glutathione.

Kev tiv thaiv thiab kho kab mob cataracts: Hauv ophthalmology, glutathione tuaj yeem siv los tiv thaiv thiab kho kab mob cataracts. Kev tshawb fawb qhia tau hais tias qhov tshwm sim ntawm cataracts yog ze ze rau oxidative puas nyob rau hauv lub lens. Raws li cov tshuaj antioxidant, glutathione tuaj yeem txo qhov cuam tshuam ntawm oxidative kev puas tsuaj ntawm lub lens hlwb thiab tswj lub cev ua haujlwm ntawm lub lens. Piv txwv li, nyob rau hauv ib txoj kev tshawb no, qhov muag tee uas muaj glutathione tau siv los kho cov neeg mob cataract, thiab nws tau pom tias cov qib ntawm lub lens opacity ntawm cov neeg mob tau txo, thiab lawv lub zeem muag tau txhim kho rau qee yam [9].
Kev tiv thaiv thiab kev kho mob ntawm retinopathy: Retinopathy yog ib yam kab mob qhov muag, thiab nws qhov tshwm sim yog cuam tshuam nrog rau yam xws li oxidative stress thiab inflammatory teb. Glutathione tuaj yeem, los ntawm nws cov nyhuv antioxidant, txo cov oxidative puas ntawm cov ntaub so ntswg retinal, inhibit qhov inflammatory teb, thiab yog li tiv thaiv cov hlwb retinal. Tsis tas li ntawd, glutathione tuaj yeem txhawb kev ua haujlwm metabolic ntawm cov hlwb retinal thiab txhim kho lub peev xwm kho tus kheej ntawm retina [9].
5. Kev siv ntau yam sclerosis
Hauv ntau yam sclerosis, neuronal degeneration yog cuam tshuam nrog oxidative kev nyuaj siab. Dimethyl fumarate (DMF) yog ib qho kev xaiv kho qhov ncauj zoo uas tau raug pov thawj los txo cov kab mob kev ua haujlwm thiab kev loj hlob ntawm cov neeg mob rov qab-remitting ntau yam sclerosis. DMF tuaj yeem qhib qhov transcription factor nuclear erythroid 2-related factor 2 (NRF2), ua rau muaj kev nce hauv kev sib txuas ntawm lub ntsiab cellular antioxidant glutathione (GSH), thiab muaj cov txiaj ntsig tseem ceeb hauv vitro. Cov kev tshawb fawb tau pom tias DMF ua rau cov glutathione reductase (GSR), ua kom rov ua dua ntawm glutathione los ntawm inducing GSR [10].
