Resumo
A microbiota intestinal, uma comunidade complexa de microrganismos, tem emergido como modulador crucial na homeostase do hospedeiro e na resposta a doenças como o melanoma, um câncer de pele altamente agressivo. Este artigo revisa os mecanismos pelos quais a microbiota influencia o desenvolvimento, progressão e resposta terapêutica do melanoma. A interação entre a microbiota e o sistema imunológico é analisada, mostrando como os microrganismos comensais modulam a resposta imune inata e adaptativa por meio da interação com células dendríticas, macrófagos, linfócitos T, e da produção de citocinas e quimiocinas. Também se discute o impacto de metabólitos microbianos, como ácidos graxos de cadeia curta, ácidos biliares secundários e compostos fenólicos derivados da dieta, na sinalização celular e modulação do microambiente tumoral. Estrategias emergentes, como o uso de probióticos, prebióticos, antibióticos seletivos, transplante de microbiota fecal e intervenções dietéticas, são avaliadas pelo seu potencial em otimizar a resposta terapêutica e mitigar efeitos adversos. A integração de abordagens baseadas na modulação microbiana pode transformar o tratamento do melanoma, melhorando a eficácia terapêutica e a qualidade de vida dos pacientes. Futuras pesquisas devem focar na personalização dessas intervenções, considerando a composição microbiana individual dos pacientes e os mecanismos subjacentes a essas interações.
