RESEARCH PRODUCT

Dabīgu imūnmodulatoru kvalitātes kontroles metožu izvērtējums un stimulējošās iedarbības salīdzinājums ar baktēriju endotoksīnu

subject

dabīgi imūnmodulatori mononukleārās šūnas AMP dezamināze Bioloģija baktēriju endotoksīns TNF alpha

description

Darba mērķis bija raksturot dabīga imūnmodulatora AMP dezamināzes aktivitāti saturoša glikoproteīnu kompleksa (AMPD) darbību in vitro un novērtēt, vai šī iedarbība nav saistīta ar iespējamo endotoksīna (LPS) piesārņojumu. Tika izvērtētas AMPD attīrīšanas metodes, salīdzināta AMPD, LPS un lentināna ietekme uz iekaisuma citokīnu sekrēciju mononukleārajās šūnās, kā arī uz dermas fibroblastu proliferāciju. AMPD frakcijas sastāvs un polisaharīda daļas iespējami strukturālā līdzība ar LPS sarežģīja kvalitātes kontroli. Tāpat kā LPS, AMPD stimulēja TNF un IL-6 produkciju un veicināja dermas fibroblastu proliferāciju ar imūnšūnu sekretēto proteīnu starpniecību. LPS neitralizēšanai izmantojamās metodes maz ietekmēja AMPD imūnstimulējošo darbību, kas norāda, ka tā neveidojas endotoksīna piesārņojuma rezultātā.
