Sunta Ricin (RT) waa tan labaad ee ugu halista badan ee loo yaqaan;waxaa CDC u magacawday wakiil la doortay.RT waxaa sameeyay dhirta bean castor;qiyaastii 50,000 oo tan oo RT ah ayaa la soo saaraa sannadkii iyadoo laga soo saaray saliidda castor.RT waxay leedahay laba qaybood, silsilad ribotoxic A (RTA) iyo silsiladda galactose-binding B (RTB).RT waxay ku xidhaa dhammaan unugyada naasleyda oo mar gudaha la galiyo, hal RTA ayaa si firfircoon u hawlgelisa dhammaan ribosomes-yada unugga.Waxaa loo maamulaa sida aerosol, RT waxay keentaa dhaawac sambabada oo degdeg ah iyo fibrosis oo ay ku xigto dhimasho.Ma jiraan tallaalo uu ansixiyay Maamulka Cuntada iyo Dawooyinka iyo daawaynta ayaa wax ku ool ah oo keliya saacadaha ugu horreeya ka dib soo-gaadhista.Waxaan samaynay tallaal dib-u-habayn ah oo RTA ah kaas oo leh laba beddelaad V76M/Y80A (RiVax).Borootiinka waxaa lagu muujiyey Escherichia coli oo waa aan sun ahayn oo difaac u ah jiirarka, bakaylaha, iyo aadanaha.Marka jiirarka la tallaalay lagula tartamo la duro, hawada laga sii daayo, ama afka laga maamulo (gavaged) RT, si buuxda ayaa loo ilaaliyaa.Waxaan hadda dejinay qaab kuleylaha, aluminium-adjuvant-ka kooban ee RiVax waxaana ku tijaabinay macaques rhesus ah.Saddex irbadood ka dib, xayawaanku waxay soo saareen unugyada difaaca jirka kuwaas oo si buuxda uga ilaaliya qiyaasta halista ah ee hawada hawada laga saaray ee RT.Unugyadan ayaa ka takhalusay RT waxayna ku tartameen heerar kala duwan guddi dhexdhexaadin ah iyo unugyo ka hortag la'aan unugyada unugyada difaaca jirka ee loo yaqaan ' epitopes' gaar ah RTA-ga hooyo.Natiijadu waxay muujinaysaa tartanka antibody-ga ee ka soo horjeeda waxay mateli kartaa saxiixa difaaca jirka.Muhiimad ahaan, isla saxeexa ayaa la arkay iyadoo la adeegsanayo sera ka timid bini'aadamka la tallaalay RiVax.
