On 24–26 October 2018, the third annual joint meeting of participants from the Institute of Immunology and Microbiology involved in programmes SVV (Specific Academic Research, no. 260369) and Progres (Q26/LF1) took place in Krkonoše. In addition to participants' presentations, a guest lecture by an expert from The Center for Advanced Preclinical Imaging, Dr. Vít Herynek, accompanied the programme. We hope to follow the tradition in the next years.
