1/20/87 arr Ron Crystal NIH [stamped, JAN 16 1987] (HIV) AIDS virus in lung cells? Has anyone looked into this? You and Gallo are handy for a collaboration. We may have to face the possibility of aerosol transmission from AIDS-patients who have concurrent bronchitis, pneumonia. You could certainly get at the most concentrated potential sources . . . and if you ever get a positive reading, then track the attenuation up the bronchial tree. Conversely, why doubt that HIV could be instilled into a lung? Or can you give some rationale on that point? Yours, Joshua.
