Introduction: there are reports of autoimmune disease related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) such neurological syndromes and hematological syndromes, and more recently autoimmune thyroid dysfunctions have been described. These reports suggest that SARS-CoV-2 acts as a pro...
ABSTRACT Background - Exposure to viral antigens that share amino acid sequence similar with self- antigens might trigger autoimmune diseases in genetically predisposed individuals, and the molecular mimicry theory suggests that epitope mimicry between the virus and human proteins can activate autoimmun...
O mecanismo de mimetismo molecular, evidenciado pela presença de reação cruzada humoral e celular entre antígenos do estreptococo e proteínas do tecido cardíaco, é postulado como principal mecanismo envolvido na patogênese da doença reumática cardíaca (DRC). Linfócitos T CD4+ infiltrantes da ...
Guillain-Barre syndrome (GBS) is a reactive, self-limited, monophasic disease triggered by a preceding bacterial or viral infection. GBS has also been linked to underlying systemic diseases, certain malignancies, surgery, pregnancy, trauma severe infection, and tissue transplantation (bone marrow and org...
Anticorpos para antígenos cardíacos foram analisados por ELISA em 14 soros de camundongos Balb/c hiperimunizados com Streptococcus mutans, inativado pelo formaldéido. Os níveis de anticorpos da classe IgG anticoraçäo e antimiosina elevaram-se significativamente nos animais imunizados quando compara...
The realization that tumor cells utilize multiple mechanisms to escape from immune recognition and destruction has stimulated interest in developing and applying immunotherapeutic strategies which target both humoral and cellular immunity to malignant cells. As a result, the tumor-associated antigens (TA...
