Immunogenic cell death (ICD) is a modality of regulated cell death that is sufficient to promote an adaptive immune response against antigens of the dying cell in an immunocompetent host. An important characteristic of ICD is the release and exposure of damage-associated molecular patterns, which are potent endogenous immune adjuvants. As the induction of ICD can be achieved with conventional cytotoxic agents, it represents a potential approach for the immunotherapy of cancer. Here, different aspects of ICD in cancer biology and treatment are reviewed.

Melanoma, the most aggressive form of skin cancer, presents a major clinical challenge due to its tendency to metastasize and recalcitrance to traditional therapies. Despite advances in surgery, chemotherapy, and radiotherapy, the outlook for advanced melanoma remains bleak, reinforcing the urgent need for more effective treatments. Photodynamic therapy (PDT) has emerged as a promising alternative, leading to targeted tumor destruction with minimal harm to surrounding tissues. In this study, the direct and abscopal antitumor effects of PDT in a bilateral murine melanoma model were evaluated. Although only one of the two tumors was treated, effects were observed in both. Our findings revealed significant changes in systemic inflammation and alterations in CD4+ and CD8+ T cell populations in treated groups, as evidenced by blood analyses and flow cytometry. High-throughput RNA sequencing (RNA-Seq) further unveiled shifts in gene expression profiles in both treated and untreated tumors. This research sheds light on the novel antitumor and abscopal effects of nanoemulsion of aluminum chloride phthalocyanine (AlPcNE)-mediated PDT in melanoma, highlighting the potential of different PDT protocols to modulate immune responses and to achieve more effective and targeted cancer treatments.

O objetivo deste estudo foi conhecer a opinião dos profissionais participantes da implantação-piloto de testes moleculares para detecção de Chlamydia trachomatis e Neisseria gonorrhoeae no Sistema Único de Saúde (SUS). Determinou-se a taxa de detecção de C. trachomatis e/ou N. gonorrhoeae e os fatores associados à infecção. A estratégia contou com laboratórios pertencentes à rede de carga viral de HIV e hepatites virais. A testagem teve como público-alvo pessoas mais vulnerabilizadas às infecções sexualmente transmissíveis, com coleta de amostras de urina e/ou swabs vaginal, endocervical e/ou uretral masculino. Questionários foram enviados aos gestores estaduais e profissionais de laboratório sobre a implantação-piloto. De maneira geral, as avaliações foram positivas. Entre as fraquezas, citou-se dificuldades na mudança do processo de trabalho, carência de recursos humanos, pouca sensibilidade de profissionais da assistência e ausência de tubo primário de urina, único insumo não fornecido. Como fortaleza, destaca-se aquisição centralizada de testes, compartilhamento de equipamentos e armazenamento de amostras à temperatura ambiente. Das 16.177 pessoas testadas, 1.004 (6,21%) foram positivas para C. trachomatis, 1.036 (6,4%) para N. gonorrhoeae e 239 (1,48%) para C. trachomatis/N. gonorrhoeae. A detecção de infecção ocorreu mais em pessoas jovens (≤ 24 vs. > 24 anos) (aOR = 2,65; IC95%: 2,38-2,96), do sexo masculino (aOR = 1,95; IC95%: 1,72-2,21), pardas/pretas (aOR = 1,06; IC95%: 1,05-1,11), na Região Sudeste (aOR = 1,08; IC95%: 1,02-1,13) e em amostras de secreção uretral (aOR = 1,46; IC95%: 1,41-1,52). Os resultados deste estudo demonstraram a importância da disponibilização da testagem em âmbito nacional, os quais subsidiaram a implantação da rede definitiva para detecção de C. trachomatis/N. gonorrhoeae no SUS.
