ABSTRACT
Human adenoviruses (HAdVs) are the common infectious pathogens in children, which mainly infect the respiratory tract, digestive tract and eyes.Severe HAdVs may even be life-threatening.HAdVs enter the host and cause infection by binding to the host epithelial cells.At the same time, they are recognized by various immune cells and then activate the immune defense response.This study aims to review the interaction between HAdVs and the host, and the immune defense mechanism, thus improving the understanding of the immune response to HAdVs.
ABSTRACT
In order to explore the possibility of human adenovirus infection with tree shrews,the neutralizing antibody ti-ters of five kinds of human adenoviruses (HAdv)in the serum of tree shrews were analyzed.The levels of Ad3,Ad4,Ad7, Ad14 and Ad55 neutralizing antibody were detected by virus neutralization test.The results showed that the positive rate of four adenoviruses in group B were higher than Ad4 in group E,and the positive rates respectively were Ad14 (55.88%),Ad3 (47.06%),Ad55 (29.71%),Ad7 (14.71%)and Ad4 (8.82%).The antiserum mainly mixed with Ad3,Ad14 and Ad55 anti-body.Five species of human adenovirus can be naturally infected with tree shrews.Tree shrews are used as experimental ani-mals to establish human adenovirus infection model is alternative.
