Menene Urolithin A?
Urolithin A wata postbiotic ce: wato sinadari da ƙwayoyin ƙwayoyin hanji ke sarrafa, ba abinci kai tsaye ba. ƙwayoyin cuta na hanji suna canza ellagitannins da ellagic acid – waɗanda ke cikin inabi, ƙwal, da wasu 'ya'yan itatuwa – zuwa UA.

Saboda haka, wasu mutane na iya samun ƙananan matakan UA duk da suna cin abincin da ke da ellagitannins sosai.
UA an san shi da inducer na mitophagy. Mitophagy aikin tsabtace sel ne da ke cire mitochondria da suka lalace, a maye gurbinsu da sabbi masu lafiya. Lalacewar mitochondria alama ce ta tsufa; don haka, UA ya zama abin sha’awa a cikin binciken da ke nuni da tsawon rai.
Dalilin Da Yasa Tsufan Garkuwar Jiki Ke Zama Manufa
Tsufan garkuwar jiki – immunosenescence – na nufin raguwar ƙarfi da ingancin amsar garkuwar jiki da shekaru ke ƙaruwa. Ana rasa kwayoyin T “naïve” waɗanda ke da damar ganowa da yaki da sabbin ƙwayoyin cuta, yayin da ƙwayoyin da suka riga sun zama ƙwararru ke gajiye ko su ƙara haɗuwa da inflammaging – wata ƙaramar kumburi da ke ci gaba a jiki.
Masu binciken sun mai da hankali kan lalacewar mitochondria da gajiwar ƙwayoyin tushe a matsayin manyan dalilan wannan raguwa. Binciken da ƙungiyar ta gudanar a beraye ya nuna UA na ƙara yawan memory‑stem da naïve‑like T cells. An tambayi ko irin wannan tasiri na faruwa a cikin mutane.
