RÉSUMÉ
Workshops are an important part of the IFPA annual meeting. At IFPA Meeting 2010 there were twelve themed workshops, six of which are summarized in this report. 1. The immunology workshop focused on normal and pathological functions of the maternal immune system in pregnancy. 2. The transport workshop dealt with regulation of ion and water transport across the syncytiotrophoblast of human placenta. 3. The epigenetics workshop covered DNA methylation and its potential role in regulating gene expression in placental development and disease. 4. The vascular reactivity workshop concentrated on methodological approaches used to study placental vascular function. 5. The workshop on epitheliochorial placentation covered current advances from in vivo and in vitro studies of different domestic species. 6. The proteomics workshop focused on a variety of techniques and procedures necessary for proteomic analysis and how they may be implemented for placental research.

Isolates of HTLV-I have been characterized from a number of different regions of the world; however, there has not been a nucleotide sequence analysis of an HTLV-I isolate from a South American country. Reported here is an individual from Chile identified with the HTLV-I-associated neurological disease HAM/TSP. The sera and the nucleic acid sequence of the HTLV-I present in peripheral blood lymphocytes from this Chilean HAM/TSP patient over a two year period are characterized. During this time, the patient's condition grew progressively worse. While the serological profile of this patient was unremarkable in comparison with other HAM/TSP patients previously described, nucleic acid sequence analysis identified two nucleotide positions which contained nucleotides unique to this Chilean isolate. The nucleotide sequence analysis also indicates that the Chilean HTLV-I isolate is more closely related to Caribbean and Japanese isolates of HTLV-I than to the African and U.S. isolates described so far.
