Cancer research today: immunology and the host response
digital file Black & White Sound 1974 36:04
Summary: This programme is presented as a dialogue, dealing with the specific antigenicities of tumour cell populations. The antigens are of three broad types, those associated with viral tumours, those in chemically-induced tumours, and embryonic antigens. The methods of detection of the antigens are discussed, with emphasis on the different results obtained with human tumours and the lack of suitable in vitro test systems other than with experimental animals. The failure of immune responses to dislodge tumours is discussed, as well as various means by which an anti-tumour response might be augmented in favour of the patient. 7 segments.

Description: Segment 1 Davies introduces the lecture. He and Professor Alexander are then shown seated for discussion. They explain that they are going to have a dialogue on the subject of immunology. They begin by discussing chemically induced tumours.

Further information: This tape is one of more than 120 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and early 1980s, thus constituting a contemporary medical-historical archive of great interest.
