The balancing effect between MAPK and NFκB pathways for the transcriptional regulation of Toll-like receptorsHong, Xinyang January 2016 (has links)
Toll-like receptors (TLR) are a family of pattern recognition receptors crucial for pathogen pattern recognition. Upon activation, TLRs induce innate immune responses such as cytokine production. However irregular TLR activities can provide fatal, hence fine tuning of the TLR induced responses are necessary. The TLR mediated immune responses are controlled by the positive/negative regulation of TLR signalling pathways, relocation of TLR proteins and modulation of TLR transcription. Systematic analyses of the agonist-induced transcriptional changes of TLRs were shown for the first time in my thesis. In my experiments, I have shown that each agonist induced a unique pattern of TLR transcription. Following PAM stimulation, mRNA levels of the cognate TLR1/2 increased whereas mRNA levels of the cross-regulating TLR4, 7/8/9 reduced in both cell lines and splenic macrophages from different mice strains. Through investigation of the signalling pathways responsible for mediating such TLR transcriptional changes, I then discovered the balancing effect between NFÎoB and MAPK signalling pathways. PAM induced TLR transcriptional changes were controlled by the additive and/or antagonistic interference between MAPK signalling cascades, ERK, JNK, P38 and NFÎoB signalling pathways. This was the first time that signalling synergy between MAPK and NFÎoB pathways were shown. Furthermore, PAM induced transcription of TLR1 and TLR8 may be partially regulated by the indirect feedback mediated by protein production. Importantly, the maintenance of the basal TLR mRNA expression also required activation of both MAPK and NFÎoB signalling pathways. In addition, signalling control for TLR transcription induced by different agonists (PAM vs. LPS) or in different species (chicken vs. mice) was compared. LPS induced transcriptional changes of the cross-regulating TLR1/2 and 3 but not the cognate TLR4 in RAW cells. The LPS induced TLR transcriptional changes required activation of a combination of MAPK and NFÎoB signalling pathways which shared both similarities and differences to the PAM induced signalling activation. In chicken, PAM induced more potent signalling activation, regulating the TLR transcriptional changes at a lower concentration than in mice. Overall, this thesis demonstrates that the transcriptional regulation of TLRs is complex, mediated by the coordination between MAPK and NFÎoB signalling pathways. These studies have significant implications in providing detailed insight of TLR transcriptional regulation which plays an important role in the regulation of TLR mediated innate immune responses.

desenvolverem a doença clínica sugere que fatores genéticos podem desempenhar um papel
importante na patogênese da TB. Polimorfismos em genes de citocinas têm sido associados
com susceptibilidade, gravidade e variação na resposta clínica em várias doenças, incluindo
doenças infecciosas. Para combater a doença, a única vacina licenciada para uso contra a
tuberculose é o Bacilo de Calmette-Guérin (BCG). A proteção induzida pela vacinação contra
o M. tuberculosis é mediada pela geração de células T específicas e produção aumentada de
IFN-γ. Objetivo: Avaliar a associação entre o polimorfismo de genes de citocinas e
receptores em voluntários sadios revacinados com BCG ao perfil de resposta in vitro a
antígenos micobacterianos. Metodologia: 25 voluntários com resultados negativos ao teste
tuberculínico em dupla testagem (que fizeram parte de um estudo de revacinação com Bacilo
de Calmette-Guérin, cepa Moreau), foram recrutados para o estudo. As citocinas IFN-γ, TNF,
IL-10, IL-6 e IL-1β foram avaliadas no sobrenadante das culturas de sangue total estimuladas
com antígenos do M. tuberculosis. Os polimorfismos de interesse IFNG +874T>A, IL10-
592C>A, IL1B-35C>T, TLR2 G753A (Arg753Gln) e TLR4 C399T (Thr399Ile) foram
amplificadas por reação em cadeia da polimerase (PCR) e a análise dos polimorfismos foram
identificados por tamanho dos fragmentos de restrição (PCR-RFLP) ou Amplificação pelo
Sistema de Mutação Refratária (ARMS-PCR). Resultados: Não houve diferença significativa
na produção das citocinas IFN-γ, IL-10, TNF, IL-6 e IL-1β antes ou após a revacinação com
BCG entre os diferentes genótipos dos polimorfismos estudados. Discussão e Conclusão: No
presente estudo, foi observado que o aumento da produção de IFN-γ (estudo de revacinação
com Bacilo de Calmette-Guérin, cepa Moreau) após a revacinação de indivíduos saudáveis
com BCG não foi influenciada por polimorfismos previamente associados com resistência
e/ou susceptibilidade ao desenvolvimento da tuberculose em outras populações. / Salvador
