Baboons are less LPS-sensitive than humans, even though their immune r
esponse mechanisms are similar. Since TNF alpha is a central mediator
of the LPS-response we cloned and sequenced the baboon TNF alpha cDNA
and compared the resulting sequence with the human TNF alpha sequence.
Analysis of the TNF alpha protein coding region indicated 97% homolog
y and of the 3' UTF 89%. The predicted baboon TNF alpha amino acid seq
uence differed at 10 positions from the human sequence. ''TA'' rich mo
tifs within the 3' UTR were 100% homologous. (C) 1997 Elsevier Science
