On 11–13 October 2017, the joint meeting of students and researchers from the Institute of Immunology and Microbiology involved in programmes SVV (Specific Academic Research, no. 260369) and Progres (Q26/LF1) took place in Krkonoše for the second time. Participants' presentations were once again accompanied by a lecture from our guest, this time an expert in proteomics and mass spectrometry, doc. RNDr. Jiří Petrák, Ph.D. (project head of the Clinical Proteomics section, BIOCEV). We hope that this event will become a tradition and we will meet again in the upcoming years!
