Experimental infections with Paracoccidioides brasiliensis obtained from armadi...
Nishikaku,Angela Satie; Peraçoli,Maria Terezinha S.; Bagagli,Eduardo; Sugizaki,Maria Fátima; Sartori,AlexandrinaParacoccidioides brasiliensis causes paracoccidioidomycosis (PCM) that is one of the most prevalent systemic human mycoses in Latin America. Armadillos show a high incidence of PCM infection and could, therefore, be a natural reservoir for this fungus. In this study were compared the virulence profiles of isolates obtained from nine-banded armadillos (Dasypus novemcinctus) (PbT1 and PbT4) and isolates from PCM ...
Immunologic aspects of West syndrome and evidence of plasma inhibitory effects ...
Montelli,Terezinha C.B.; Soares,Angela M.V.C.; Peraçoli,Maria Terezinha S.STUDY OBJECTIVE: The purpose of this study was to assess the extent of immune dysfunction in a well-defined group of epileptic patients: children with diagnosis of West syndrome (WS) or with transitions to another age-related EEG patterns, the multifocal independent spikes (MIS), and the slow spike-wave complexes (Lennox-Gastaut syndrome - LGS). Thus, WS was studied at different points of the natural evolutive ...
Familial cancer: depressed NK-cell cytotoxicity in healthy and cancer affected ...
Montelli,Terezinha C.B.; Peraçoli,Maria Terezinha S.; Gabarra,Roberto C.; Soares,Angela M.V.C.; Kurokawa,Cilmery SuemiDepressed natural killer (NK) cell activity has been showed in family members of patients with different types of cancer. The present work aimed to evaluate T cell subsets and NK cell cytotoxic activity in 15 members of a family with high incidence of tumors, such as glioblastoma, gastric, pancreas and colon rectal carcinoma, chronic myelocitic leukemia, melanoma and osteoblastoma. As controls, 19 healthy subje...
Alterations of cell-mediated immune response in children with febrile seizures
Montelli,Terezinha C.B.; Soares,Angela M.V.C.; Parise-Fortes,Maria R.; Rezkallah-Iwasso,Maria T.; Padula,Niura M.R.; Peraçoli,Maria Terezinha S.The aim of the present investigation was to study the distribution of T-cell subsets in peripheral blood defined by monoclonal antibodies and by the lymphocyte proliferative response to phytohemagglutinin (PH A) in 30 children with febrile seizures and in 14 age-matched control subjects. Frequent respiratory, urinary and dermatologic infections were observed in 22 patients. The immunologic parameters showed tha...
Cell-mediated and humoral immunity in west syndrome
Montelli,Terezinha C. B.; Iwasso,Maria Tereza R.; Peraçoli,Maria Terezinha S.; Mota,Norma Gerusa S.The immunological status of five children with West syndrome consequent to previous cerebral lesions was investigated. Three children had West syndrome and two were in transition from West to Lennox-Gastaut syndrome. All of them showed cellular immunological deficiencies in the following tests: sensitization to DNCB, intracutaneous reaction to PHA, inhibition of leucocyte migration, blastic transformation of ly...
