Ngaba inzululwazi iya kusihlangula kwiphupha lokwaluphala?

Ngaba inzululwazi iya kusihlangula kwiphupha lokwaluphala?

Iminyaka iyahamba kwaye iimpawu zokwaluphala ziqala ukubonakala kuthi. Akukho budala bokubaleka. Ukusukela ngo-2015, siye sabona ukutsiba kwenzululwazi okusemgangathweni kunye nokungazange kubonwe ngaphambili malunga neetafile ezilwa nokuguga kwaye zicothise isantya sakho.

Kwintsha, ngokutsho kwapapashwa kwi-Journal of Scientific Reports, echaza uphando olwenziwa yiYunivesithi yaseLeicester, eNgilani, izazinzulu ziye zakwazi ukuphucula ukusebenza kunye nokhuseleko lwamachiza "aguga analyzer" ukunyanga amajoni omzimba ngokuchaneka okuvumela. ukuba bajolise kwiiseli ezingasebenziyo ngaphandle kokwenzakalisa iiseli ezisempilweni.

Amandla amakhulu onyango lokulwa nokuguga lukwaxhomekeke ekukwazini ukujolisa kwizinto ezibizwa ngokuba ziiseli ze-senescent, oko kukuthi, ezo ziphulukene namandla okwahlula kunye nokuqokelela emzimbeni kunye nokukhawulezisa inkqubo yokuguga.

Ngelixa ukuqokelelana kweeseli ze-senescent kuyinxalenye eqhelekileyo yenkqubo yokuguga, izazinzulu zenze amanyathelo anomdla malunga nendlela yokususa ezi seli emzimbeni usebenzisa amayeza enziwe ngenjongo.

"Ixesha lempilo"

Izidakamizwa zeGeriatric ziye zaboniswa ukuba zihlaziye iiseli ezindala kwiigundane kwaye zandise ixesha lokuphila kwazo, ngelixa inkqubela phambili ethembisayo iye yenziwa ekusebenziseni ukuphucula oko kwaziwa ngokuba yimpilo ephilileyo.

Kwaye kwinyanga ephelileyo ibone imodeli eyothusayo, apho izazinzulu zibonise indlela "iziyobisi" ezinokuthi zisuse iiseli ezigugayo kwimiqolo yezilwanyana (ezilingwayo) kwiminyaka yobudala kwaye zidale indawo yokuba iiseli ezintsha, ezisempilweni zikhule, zikhulise ukubakho kwento entsha. unyango lweentlungu zomqolo ezingapheliyo ebantwini.

ukudubula random

Iqela lezenzululwazi zamazwe ngamazwe emva kolu phononongo lwamva nje lijolise kwinto abayibonayo njengesiphene kwisizukulwana sangoku seziyobisi "zokuhlaziya ukuguga", njengoko besithi bathatha indlela yokudubula iibhulethi ezingafunekiyo kwimipu ezifuna ukuchaneka ngakumbi kunye nokukhetha, ngokutsho. inkcazelo yabo.

USalvador McCabe, umphandi oyintloko weYunivesithi yaseLeicester wathi: “Amayeza eGerolysis ludidi olutsha lwamayeza anokuthomalalisa iimpawu zokwaluphala. Kodwa kukho iziphumo ebezingalindelekanga ezinamandla ukuza kuthi ga ngoku, kwaye ngaloo ndlela kuqaqambise ukubaluleka kwesizukulwana sesibini samachiza alwa nokuguga, ajolise kwiiseli ezigugayo ngaphandle kokuchaphazela ezinye iiseli.

Olu phuhliso lungazange lubonwe ngaphambili lwakha kuphando lwangaphambili liqela leenzululwazi zeYunivesithi yaseLeicester, echonge i-membrane marker kwiiseli ze-senescent kwaye yabonisa indlela ezinokujoliswa ngayo ukuze ziphelise ngomgangatho ophezulu wokuchaneka, okwenza kube lula ukuphuhlisa i-compound entsha. i-antibody elayishwe ngamachiza e-cytotoxic.

iziphumo ezithembisayo

Ukongezelela, iimvavanyo ezikhethiweyo zobungqina bombono ziye zabuyisela iziphumo ezithembisayo, apho umphumo odibeneyo we-antibodies kunye neziyobisi zifana "nebhomu ehlakaniphile", iiseli eziguga zichongiwe kwaye zipheliswe ngamachiza anetyhefu ukuba azikhuphe kwi-equation.

Izazinzulu ziqinisekisile ukuba unyango aluzange lube nefuthe kwiiseli ezingabonakaliyo, ezinempembelelo entle ekuchanekeni nasekukhuseleni unyango.

Indlela yombono kunyango lomhlaza

“Ngokukopa umbono osele usetyenziswa kunyango lomhlaza, i-antibody itshintshiwe ukuze ikwazi ukubona ezi seli kwaye ikhuphe intlawulo enetyhefu ngaphakathi kuzo,” wongeze watsho uMcCabe.

Izazinzulu zathi le ndlela intsha ngokupheleleyo yokulahla iiseli ezalupheleyo, zichaza ukuba banethemba lokuphinda le mpumelelo nabantu ngenye imini, begxininisa ukuba baya kusebenzisa ezi ziphumo njengesiseko sokufunda ngakumbi kunyango olujoliswe ngakumbi lokuguga.
