Natural immunity to rotavirus infection in children.
Annual deaths in infants and young children due to rotavirus (RV) infection are around 100,000 in India and about 600,000 globally. Development of a vaccine for this disease is a high priority. The protective mechanisms for RV diarrhea in human are not fully understood, but it is known that children develop natural immunity against RV. Early exposure to RV results in most severe episode of diar...
متن کاملImmunity to rotavirus infection in mice.
Recent findings from our laboratory regarding the immune response of mice to rotavirus (a mucosal pathogen) show that although in most situations an acquired (T or B cell or both) response is necessary for elimination of primary rotavirus infection, unidentified innate mechanisms can also play a role in some mouse strains. Similar to what is seen with many other viruses, CD8+ T cells appear to ...
متن کاملModeling human enteric dysbiosis and rotavirus immunity in gnotobiotic pigs
BACKGROUND Rotavirus vaccines have poor efficacy in infants from low- and middle-income countries. Gut microbiota is thought to influence the immune response to oral vaccines. Thus, we developed a gnotobiotic (Gn) pig model of enteric dysbiosis to study the effects of human gut microbiota (HGM) on immune responses to rotavirus vaccination, and the effects of rotavirus challenge on the HGM by co...
متن کاملhumoral immunity to human neoplasms
using complement fixation technique, serial serum samples from 15 patients undergoing surgical removal of malignant tumors were assayed for the presence of tumors antibodies against the cellular fractions of both normal and carcinomatous tissue. antibody responses against tumor associated antigens were detected in four cases. in all cases antibody activity was directed only against the supernat...
متن کاملBovine milk immunoglobulins for passive immunity to infantile rotavirus gastroenteritis.
Pregnant cows were successfully hyperimmunized with all four human rotavirus serotypes, resulting in a 100-fold increase in neutralizing milk antibody titers over those of controls. Milk antibodies were isolated batchwise from 1,000 kg of pooled milk for the first 10 lactation days, yielding 10 kg of freeze-dried milk immunoglobulin concentrate consisting of 50% bovine milk immunoglobulins. Mil...
