Abstract:
After recovery from a hepatitis B virus (HBV) infection, reactivation can occur with immunosuppression; thus, it is assumed that replication competent HBV persists in the liver. We sought to detect persistent HBV from 13 people with spontaneous recovery. We quantified HBV DNA and RNA in core liver biopsy specimens (median, 1.72 × 106 cells) from persons who inject drugs. Of 13 biopsy specimens, 8 (61%) had evidence of HBV DNA or RNA and 5 (38%) had both HBV DNA and RNA. Messenger RNAs were derived from covalently closed circular DNA and integrated HBV DNA. Here, we show prevalent HBV DNA and RNA despite clinical recovery in persons who inject drugs.

What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...
