Selection and characterisation of acyclovir-resistant herpes simplex virus type 1 mutants inducing altered DNA polymerase activities.

abstract：:J-chain-deficient (Jch(-/-)) mice were used to study the role of polymeric IgA (pIgA) in primary disease and protective immunity following genital herpes simplex type 2 (HSV-2) infection. Vaginal IgA in the Jch(-/-) mice was composed primarily of monomeric IgA and was not associated with secretory component (SC). In c...
