On October 11-13 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, Dr. Jiří Petrák (1. LF UK, BIOCEV). We hope that this event will become a tradition and we will meet again in the upcoming years!
