We determined the levels of adenovirus 5 (Ad5) neutralizing antibodies in children in India less than 2 years of age. The results clearly show an age-dependent increase in Ad5-specific immunity, with 7- to 12-month-old children having the lowest levels of Ad5 immunity. This opens up the scope for the use of recombinant Ad5-based vaccines in this age group.
There are formidable challenges in developing HIV vaccines that elicit potent neutralizing antibodies against a broad array of HIV-1 isolates. The key targets for these neutralizing antibodies are the viral envelope antigens gp120 and gp41. Although broadly reactive neutralizing epitopes on gp120 and gp41 have been mapped and studied extensively, these epitopes are poorly immunogenic. Indeed, v...
Dengue is a mosquito-borne flavivirus that is spreading at an unprecedented rate and has developed into a major health and economic burden in over 50 countries. Even though infected individuals develop potent and long-lasting serotype-specific neutralizing antibodies (Abs), the epitopes engaged by human neutralizing Abs have not been identified. Here, we demonstrate that the dengue virus (DENV)...
We have very limited information on serum neutralizing antibody in women naturally infected with the human papillomaviruses (HPVs) that are causally associated with cervical cancer. In this study, serum samples collected from 217 Japanese women with low-grade cervical intraepithelial neoplasia were examined for their neutralizing activities against HPV16, -18, -31, -52, and -58 pseudovirions. E...
Our understanding of the humoral immune response to hepatitis C virus (HCV) is limited because the virus can be studied only in humans and chimpanzees and because previously described neutralization assays have not been robust or simple to perform. Nevertheless, epidemiologic and laboratory studies suggested that neutralizing Ab to HCV might be important in preventing infection. We have recentl...
Mouse cells contain several biologically distinguishable endogenous type-C viruses. In the present studies, the immunologic response of different strains of mice to the natural expression of these viruses has been examined. High titers of neutralizing antibodies have been detected to a class of virus that lacks the ability to exogenously infect mouse cells. The expression of this virus, in vivo...
