In the mid 1970's Robert Gallo and his associates claimed proof for the existence of the first human retrovirus, HL23V.

They found reverse transcriptase activity in the uncultured lymphocytes of a patient with leukaemia.

When the cell free fluids from lymphocyte cultures were banded in sucrose density gradients at the density of 1.16g/ml they found:

  1. Retrovirus like particles
  2. Reverse transcriptase activity
  3. Proteins which reacted with the patientís sera

The HL23V antibodies were confirmed by Reinhard Kurth and Robin Weiss, who concluded:

"The serological studies presented have and by others provide indirect evidence that the infectious mode of transmission remains a real possibility in humans, and suggest that infection with an oncovirus [retrovirus] may be extremely widespread"
