CAMOIP: A Web Server for Comprehensive Analysis on Multi-Omics of Immunotherapy in Pan-cancer

Immune checkpoint inhibitors (ICIs) have completely changed the therapeutic approach for tumor patients. Immunotherapy has also produced much needed data about mutation, expression, and prognosis, providing an unprecedented opportunity for discovering candidate drug targets and screening for immunotherapy-relevant biomarkers. Although existing web tools enable biologists to analyze the expression, mutation, and prognosis data on tumors, they are currently not able to carry out data mining and mechanism analyses related to immune checkpoint therapy. Thus, we developed our own web-based tool called Comprehensive Analysis on Multi-Omics of Immunotherapy in Pan-cancer (CAMOIP), in which we can screen prognostic markers and analyze the mechanisms involved with markers and immunotherapy (more than 4000 patients). The analyses include survival analysis, expression analysis, drug sensitivity analysis, mutational landscape, immune checkpoint analysis, immune related signature analysis, immune cell analysis, immune gene analysis, immunogenicity analysis and gene sets enrichment analysis (GSEA). This comprehensive analysis of biomarkers for immunotherapy can be carried out by a click of CAMOIP, and the software should greatly encourage the further development of immunotherapy. CAMOIP fills the gap between the big data of cancer genomics based on immunotherapy and providing comprehensive information to users, helping to release the value of current ICI-treated data resources. CAMOIP can be found in https://www.camoip.net.

Experimental infection characteristics of Bordetella pertussis via aerosol challenge on rhesus macaques

The effect of aerosol challenge of rhesus macaques with Bordetella pertussis and the feasibility of using rhesus monkeys as an animal model for pertussis infection were evaluated in this study. Four 1-year old rhesus macaques were aerosol challenged with B. pertussis at the concentration of 105 CFU/mL for 30 min (group 1) or 60 min (group 2). Rectal temperature was found slightly increased at days 3 and 5 and returned to baseline levels at day 21 after challenge. White blood cell counts peaked at day 7, with a 4.7~6.1-fold increase and returned to baseline levels at day 45. Bacteria colonization of nasopharyngeal swabs was observed, and the number of colonies was gradually increased and peaked at day 14, reaching 5.4-8.1 x 106/mL. The seroconversion rate of anti-pertussis toxin (PT), pertactin (PRN), and filamentous hemagglutinin(FHA) antibodies was 100%, with an increase in geometric mean titers after challenge. Analysis of cytokines revealed that the levels of cytokines including IL-2, IL-6, IL-8, IL-10, IL-17A, IL-13, IL-12, and IL-18 were significantly increased at days 5 to 14 in group 2. These results demonstrate that the characteristic of pertussis infection in infant rhesus macaque was similar as in human beings, which provide a clue to using infant rhesus macaque as a candidate model for pertussis infection in the future studies
