REVIEW OF THE ACTIVITIES OF THE PAHO/WHO IMMUNOLOGY

RESEARCH AND TRAINING CENTER IN SAO PAULO*

The PAHO/WHO Immunology Research and Training Center (IRTC) in S. Paulo was established in 1966 in the De- partment of , Immunology and of the Escola Paulista de Medicina under the direction of Professor Otto G. Bier. In 1969, following on agreement between WHO, the Secretariat of Health of the

State of S. Paulo and the University of S. Paulo, the Center moved its headquarters to the Butantan Institute. The present staff of the Center is made up by Dr. Ivan Moto, Director, and Associate Professor of the University of S. Paulo, and three full-time immunologists, provided by Instituto Butantan in accordance with the agreement between WHO, the University of S. Paulo and the Secretariat of Health of the State of S. Paulo. The three immunologists ore: Dr. Mahasti S. de Macedo, Dr. Adenir Perini and Dr. Harumi Ando Takehara. At the twelfth meeting of the odvisory Committee on Medical Research in 1973 we reviewed the activities of the Center from 1970 to 1973. The present report summari ze the activities of the Center since it was established in 1966, with emphasis on the lost 3 years.

OBJECTIVES OF THE CENTER

The principal objective of the Center is to provide can- didates from Latin American countries with postgradodte teaching in basic Immunology and to carry on immunological research projects directly or indirectly related to health problems in the region.

TEACHING ACTIVITIES

COURSE ON BASIC IMMUNOLOGY. The S. Paulo IRTC holds annuolly a 4-month course on basic Immunology given by lo cal and invited visiting-professors. The course in given almost entirely in English and comprises approximately 140 hours of theoretical lectures, 105 hours of seminars and at least 320 hours of laboratory work. Up to the present time the S. Paulo IRTC has held 10 Courses on Basic Immuno logy. As con be seen in Table I most of the students who attended these Courses are presently working in the field of Immunology.

As a consequence of the Course on Basic Immunolo- gists many distinguished Immunologists have come to S. Paulo, as visiting professors to teach in the Course. During their stay in Brazil these immunologists have the opportunity of getting in contact with Brazilian immunolo- (3

giste in the state of S. Paulo as well as in other states.

In this way they exert a positive influence on many immuno logy centers beside the S. Paulo IRTC. The following

Visiting-Professors have given lectures in the S. Paulo IRTC: J. A. Andrade, Department of Endocrinology, Hospital

POSTGRADUATED STUDENTS. Due to agreements with the Uni- versity of Sao Paulo, (Prof. Celeste Fava Neto) and the

Escolo Paulista de Medicina (Prof. Nelson Mendes) students on the posgraduate Course in Immunology of both the

University of Sao Paulo and of the Escola Paulista de Medi cina (a federal school) are accepted as fellows in the IRTC to carry on their research projects. These students work in the Center doing research for 2 to 3 years and are usually supported with a fellowship from FAPESP, CAPES, or

CNPq.. Since 1971 13 ,tudents have been accepted to work on their research projects in the IRTC. Four of these studente have concluded their stay satisfactorily and have presented the results of their investigations in their Master Degree Thesis. (7

RESEARCH ACTIVITIES

Although the S. Paulo IRTC has tackled many differents research problema since its establishment (see list of published papera), more recently the researches have been concentrated on problemsa of immediate hypersensitivity and Chagas' disease. For the atudy of experimental Chagas' disease a laboratory was set up in 1973 and is actively doing research on this problem. Dr. Harumi A. Takehara is the Head of this laboratory. The following research activities are in progress at the present time: a) Isolation and choracterization of the homocytotropic antibodies of the guinea pig. Work being done by Sergio Marangoni (fellow of FAPESP), Adenir Perini, Benedito de Oliveira Filho (Prof. of Immunology, State University of Campinas, S. Paulo) and I. Mota. b) Biological properties of the lymphocytosis promoting factor isolated from Bordetella pertussis. Work being done by Vilma Trindade (Postgraduate atudent working in the Center). (8

c) Role of macrophage in the production of homocytotropic

antibodies. Effect of an specific anti-macrophage serum. Work being done by Eugenia Lagus (Student, postgraduate Immunology Course, Escola Paulista de Medicina). d) Attempts ta vaccinate mice against T. cruzi with pre- treatment with Leptomos pessoai. Work being done by Harumi

Ando Takehara. The initial part of this work was made in collaboration with Dr. W. Dias do Silva, from the Laboratory of Immunobiology; Instituto Butantan.

e) Attempts to protect mice against T. cruzi with superna- tants of lymphoid cells obtained from mice chronically infected with T. cruzi. Work being done by Harumi Ando

Takehara and Maria Elisa Pupo (Biologist, voluntary assistant

in the IRTC.

f) Role of the mononyclear phagocytic system in experimental

Chagas' disease. It is known that the effect of many immu- nostimulanta; is directed partly upon the antigen processing by the macrophage, a cell that probably has a key role in the

imnunopathology of Chagas' disease. On the other hand it has been shown recently that druga capable of raising the levels of intracellular cyclic AMP inhibits phagocytosis whereas druga capable of reducing the level of the same enzi- me system are potent atimulatora of phagocytosis. Thus, it was decided to investigate whether such drugs has any (9

beneficial effect on the course of experimental Chagos' disease.

Work been done by A. Perini, Rodolfo P'ereira

Mendes and I. Mota.

g) Attempts to immunize mice against a letal dose of T. cruzi by pretreatment of the animals with L. pessoai plus adjuvants. Work been done by Mario Eliza Pinheiro and I. Mota.

INFLUENCE OF THE CENTER ON LOCAL IMMUNOLOGY

As a result of the establishoment of the IRTC in S. Paulo and of the stimulus provided by the visiting-professors a special interest in Immunology was generated with definite pratical consequences. As a result of the solid immunolo- gical background adquired in the Course on Basic Immunology many of the atudenta decisively focused their interest in immunology research and some of them were sent abroad for further training in high level laboratories, in Europe and the United States. (unfortunately many of these students did not return to their place of origin). In this way the

IRTC is accomplishing its rolo of selecting good candidates to become future first clasa researchers in the field of

Immunology. As a example of this let us quote one student of the 1968 Course (Dr. Celso Bianco) who is now a well known immunologist and has come for several years to give lectures on Cellular Immunology in the IRTC.

A further indication of the influence exerted by the IRTC in the developement of Immunology in S. Paulo is the strong group of immunologists now working a the Institu to Biologico in S. Paulo. In that Institution are being developed research projecta on immunogenetics and on immu- noglobulins of different animal species with the collabora- tion of two visiting-professors of the IRTC Immunology Course and of one former member of the permanent staff of the Center. (14

As further consequences of the establishment of the IRTC in S. Paulo it is atill possible to quote: a) The foundation of the Sociedode Brasileira de Imunologia,

SBI (Brazilion Society for Immunology), in 1972. The initi al idea, discussiona and deliberationa for the establishment of the SBI took place in the IRTC. Indeed, presently the

SBI has its headquartera provisorily located in the IRTC. With the support of the IRTC and the Brazilian Academy of

Sciences, the SBI was able to hold the first National Sympo- sium on Immunology in Rio de Janeiro, in 1973 and a second Symposium in 1974. b) The establishment of a new laboratory in Instituto Butan-

tan, the Laboratory for Immunobiology. The new laboratory has among its finalities to improve the preparation of immunobiological materials such as and antisera.

This laboratory is functioning in close association with the IRTC taking advantages of the facilities available at the

Center to modernize the Butantan Institute's methods of preparation of immunobiological reagents.

Thumathe Immunology Research and Training Center in

S. Paulo is accomplishing to the best of its ability the boals of training investigatora and atimulating immunology research in Latin American countries. a (i ·., o b a uO o .4 sc .4 4' O b C 3 e .4 .4 4' Y u .04 u ,4 m or .4 o ...I 1.4C u e eO u >.
