1. Hypogammaglobulinemia: a diagnosis that must not be overlooked
Humoral immunological defects are frequent and important causes of hypogammaglobulinemia, leading to recurrent infections, autoimmunity, allergies, and neoplasias. Usually, its onset occurs in childhood or during the second and third decades of life; however, the diagnosis is made, on average, 6 to 7 years afterwards. As a consequence, antibody defects can l

2. Células T reguladoras na asma experimental. / Regulatory T cells in the experimental asthma.
Células T reguladoras (Treg) são cruciais na tolerância periférica e no controle da inflamação. Nós usamos dois modelos bem estabelecidos de tolerância de mucosas para a asma alérgica e a tolerância inalatória local induzida pela exposição crônica a OVA para estudar o aparecimento e função das Treg. Nós mostramos que a tolerância nasal dist

3. Fatores genéticos, exposição ambiental, mecanismos imunológicos e o desenvolvimento da sibilância e da asma na infância. / Genetic factors, environmental exposure, immune mechanisms and development of wheezing and asthma in childhood.
Mesmo com o constante avanço no estudo da sibilância e asma, existem inúmeras controvérsias sobre a participação da exposição à endotoxina, background genético e ativação celular. Investigamos a participação da exposição à endotoxina ambiental e o papel do LPS no desenvolvimento dos fenótipos de sibilância e asma. Para tanto selecionamos c

4. Innate immunity in fatal asthma / Imunidade inata na asma fatal
INTRODUÇÃO: A inflamação das vias aéreas na asma envolve respostas imunes inatas. Os receptores do tipo Toll (Toll-like receptors, TLRs) e a citocina linfopoetina do estroma tímico (thymic stromal lymphopoietin, TSLP) estão envolvidos na inflamação brônquica da asma, mas a expressão destas proteínas em vias aéreas grandes e pequenas de asmático

5. Os efeitos de um programa de exercícios respiratórios para idosos asmáticos / The effects of a respiratory exercise program tailored for elderly people with asthma
INTRODUCTION: People can develop asthma at any given age, and asthma prevalence in older adults is no different than that observed in younger people. Asthma in older adults is frequently underdiagnosed, and this is reflected in the fact that approximately 60% of people who die from asthma have surpassed the age of 65. Equally important is the fact that reduc

6. Atividade acaricida contra ácaros Dermatophagoides pteronyssinus e D. farinae (Pyroglyphidae) de produto contendo óleos essenciais de Lavadula officinalis e Mentha piperita (Labiatae) / Acaricide activity against mite Dermatophagoides pteronyssinus and D. farinae (Pyroglyphidae) of na herbal product containg essential oils from Lavadula officinalis and Mentha piperita (Labiatae)
House dust mites (HDM) are the greatest source of indoor allergens in Brazil, being closely implicated in respiratory allergic diseases such as asthma and rhinitis. In dwellings, HDM allergens are mainly found on mattresses, sofas and rug surfaces, where several methods such as mattress-covers and acaricides, can be used to control indoor mite infestation. T

7. Immunology Interaction fetal-maternal in asthma: immunological reactive patterns in blood and colostrum from healthy and asthmatic mothers and in blood from their respective newborns. / Imunologia das interações materno-fetais na asma: padrões de reatividade imunológica no colostro e no sangue de mães asmáticas e no sangue de cordão de seus respectivos recém-nascidos.
Asthma has been presenting higher prevalence rates worldwide. The objective of this work is to evaluate the presence of cellular elements and humoral indicative in blood and colostrums of healthy and asthmatic mothers and in cord umbilical blood of their newborn (NB). Lower production of IgG from asthmatic mothers was observed. Dendritic cells of asthmatic m

8. Eosinofilia e IgE sÃrica total na alergia respiratÃria e parasitose Intestinal
Eosinophilia is found in many cases of atopy, and is considered essential to the perpetuation of the pathologic process that characterizes allergic asthma and rhinitis. However, eosinophilia can also exist in other diseases as leukemia, Wiskot-Aldrich Syndrome, hypersensitivity to drugs and intestinal parasitosis. In general, in allergic diseases, besides eo

9. Avaliação do BCG como adjuvante na imunoterapia específica para asmáticos / Assessment of BGC as an adjuvant in specific immunotherapy in asthmatic patients
O aumento da prevalência de doenças alérgicas como a asma, tem sido atribuído à falta de estímulos infecciosos. A atopia, que embasa as manifestações alérgicas, caracteriza-se por uma disfunção imune com predomínio da resposta do tipo Th2. Experimentos em modelos animais com micobactérias e seus produtos têm demonstrado resultados promissores n

10. Health, employment, and financial outcomes in workers with occupational asthma.
OBJECTIVE--To study the health, employment, and financial outcome of occupational asthma. DESIGN--A follow study of workers with confirmed occupational asthma. SETTING--A specialist occupational lung disease clinic. SUBJECTS--All workers had a diagnosis of occupational asthma made at least one year earlier. Diagnosis was confirmed by serial peak expiratory f

11. Control of T helper 2 cell function and allergic airway inflammation by PKCζ
Asthma is a disease of chronic airway inflammation in which T helper (Th) 2 cells play a critical role. The molecular mechanisms controlling Th2 differentiation and function are of paramount importance in biology and immunology. PKCζ has been implicated in the regulation of apoptosis and NF-κB, as well as in the control of T-dependent responses, although n
