1. Immunodeficiencies: non-infectious manifestations
Abstract Objectives: Classical immunodeficiencies are mainly characterized by infectious conditions. In recent years, manifestations related to allergy, inflammation, autoimmunity, lymphoproliferation, and malignancies related to this group of diseases have been described. The text intends to make an update on the non-infectious manifestations of the primar

2. Human Inborn Errors of Immunity (HIEI): predominantly antibody deficiencies (PADs): if you suspect it, you can detect it
Abstract Objective: This minireview gathers the scientific foundations of the literature on genetic errors in the development of the humoral immune system to help pediatricians suspect these defects. Sources: A systemic search using the PubMed MEDLINE database was performed for all Predominantly Antibody Deficiencies (PADs) described in the 2020 IUIS Exper

3. Diagnosing lymphoma in a setting with a high burden of infection: a pediatric case of Epstein-Barr virus-associated aggressive B-cell lymphoma with t(8;14) (q23;q32) and extensive necrosis mimicking tuberculosis
The association of lymphoma with necrotic granuloma can pose diagnostic challenges and delay treatment, especially in settings with a high burden of infection. In these settings, the timely use of cytogenetic and molecular methods is most relevant. Here, we report a case of B-cell lymphoma with t (8;14) in a 5-year-old male child. The lymphoma was associated

4. Effect of lipoarabinomannan from Mycobacterium avium subsp avium in Freund’s incomplete adjuvant on the immune response of cattle
The aim of the present study was to determine whether lipoarabinomannan (LAM), in combination with Freund’s incomplete adjuvant (FIA), was able to improve cell-mediated and antibody-mediated immune responses against ovalbumin (OVA) in cattle. Twenty-three calves were assigned to four treatment groups, which were subcutaneously immunized with either OVA plu

5. Obtenção de proteína recombinante baseada em antígenos do líquido vesicular de Taenia crassiceps: aplicação no imunodiagnóstico da neurocisticercose / Recombinant protein obtainment based on antigens from Taenia crassiceps vesicular fluid: application on immunodiagnostics of neurocisticercosis
A neurocisticercose (NC) é uma doença provocada por larvas de Taenia solium (Tso) no sistema nervoso central. Seu diagnóstico fundamenta-se em critérios clínicos, epidemiológicos e laboratoriais. A utilização de antígenos parasitários no imunodiagnóstico apresenta desvantagens como: necessidade de animais, ausência de homogeneidade entre lotes, b

6. Administration of the dehidroepiandrosterone (DHEA) as mediador of the immune response in Young and ageing rats infected with Trypanosoma cruzi submitted to repetitive stress. / Administração de dehidroepiandrosterona (DHEA) como mediador da resposta imune em ratos Wistar infectados com Trypanosoma cruzi submetidos ao estresse repetitivo
Chagas disease represents an important public health problem in Latin American, where the treatment is limited especially to chronic phase, besides the harmful side effects. Although controlling the parasite replication, the complete elimination of the etiologic agent still was not observed. Activation of the hypothalamuspituitaryadrenal axis plays a major r

7. Development of a method for evaluating the induction of specific immunity against tumor cells by monocytes transfection with tumor RNA. / Desenvolvimento de método de avaliação da indução de imunidade específica contra células neoplásicas pela transfecção de monócitos com RNA tumoral.
The cancer immunotherapeutic approach has been increasingly exploited. Among the factors that make it attractive, but also limited, is the use of patient antigenic material. Thus, we propose to establish conditions for extraction and amplification of mRNA tumor, as renewable source of antigens. It is also intended to assess the vaccine effectiveness, using m

8. Proliferação celular e citocinas BCG especificos em crianças com AIDS : efeito de suplementos nutricionais / BCG-specific lymphoproliferation and cytokine production in children with AIDS : effects of nutritional supplements
As crianças infectadas pelo HIV-1 despertam preocupações especiais em relação à nutrição e ao estado de saúde, pois os efeitos imunossupressores da infecção as colocam em situação de grande risco para complicações infecciosas e déficits no estado nutricional. O desenvolvimento de estratégias que visem a recuperação do estado nutricional e

9. Anaplasma marginale : análise da variabilidade do gene msp1 a e avaliação imunogênica da vacina de DNA contendo genes para MSP1a, MSP1b e MSP5 em camundongos BALB/c
Anaplasma marginale is an important tick-transmitted rickettsial pathogen of cattle that invades and multiplies within erythrocytes, causing severe hemolytic anemia during acute infection. Immunization with purified outer membrane proteins (OMP) induces protection against acute A. marginale disease. Of 21 OMP described six major surface proteins (MSPs 1a, 1b

10. Avaliação da Imunogenicidade de Dois Novos Imunobiológicos Candidatos a Vacina Contra Leishmaniose Visceral Canina
Considering the importance of immunoprophylactic strategies for the control of visceral leishmaniasis, and the lack of studies concerning the cellular and humoral events that occur during vaccination in dogs, we have attempted to evaluate the immune response of a promising new vaccines candidate against canine visceral leishmaniasis (CVL). Thirty five mongre

11. "Diagnóstico da doença de Chagas em bancos de sangue: linfoproliferação, detecção de anticorpos e estudo epidemiológico em indivíduos com provas sorológicas inconclusivas" / Diagnostic of Chagas disease in blood banks: lymphoproliferation, antibodies detection and epidemiological data in individuals with inconclusive serology
This study aims to evaluate the contribution of lymphoproliferation (1 parameter) in association with high performance serological tests (4), epidemiological data (1) and parasitological tests (1) for Chagas disease in patients with inconclusive conventional serological tests. We showed that this diagnosis is probable in individuals presenting >three positiv

12. The chemical study of biological activities from the mansoa hirsuta Bignoniaceae / Estudo químico e de atividades biológicas da mansoa hirsuta D.C (Bignoniaceae)
Plants of the Bignoniaceae family in Brazil, as Mansoa hirsuta, have medicinal use and some biological activities were already proved experimentally. This study aimed to isolate and identify compounds with activity anti-Leshmania amazonensis, anti-Tripanossoma cruzi, molluscicidal, larvicidal and immunomodulatory in plant extracts of Mansoa hirsuta D.C..
