Job description

Lyme disease (LD) or Lyme borreliosis (LB) is caused by spirochetes belonging to Borrelia burgdorferi sensu lato group and gives rise to a wide spectrum of clinical manifestations affecting multiple organ systems. The spirochetescirculate in nature in a complex enzootic cycle and primarily transmitted by hard-bodied Ixodes ticks - I. scapularis/pacificus in the U.S.A., I. ricinus in Europe and I. persulcatus in parts of Asia - and several reservoir hosts (small mammals and birds). The number of annually reported cases for tick-borne diseases (TBDs; especially LB) has been continuously increasing over the last two decades with the Centers for Disease Control and Prevention (CDC) reporting 59,349 in the United States and approximately 85,000 for LB only, in Europe. However, estimates are even higher - specifically for LB - with the number of new infections to be as high as 330,000 and 250,000 in the U.S and Europe, respectively.

LYMErix™, a vaccine against LB was available for human use in 1998 in the U.S was later withdrawn in 2002 due to negative advise and potential adverse effects. Since then, no commercial vaccine has been launched in the market, which clearly underscores the urgent need for the development of new vaccines, to prevent the rapid increase of LB and other TBDs worldwide.

The PhD student will be involved in a cutting edge project aiming to identify and characterize novel vaccine candidates that will encompass proteins from both the vector (Ixodes tick) as well as the causative pathogen (Borrelia), a double edged sword that might not only provide protection against LB, but also other TBDs. The PhD student will focus on the characterization of novel Borrelia proteins (identified as part of an ongoing project), as well as tick proteins, and describe their role in tick-host-pathogen interactions. In addition, the PhD candidate will assess immunogenicity of these vaccine candidates using different adjuvants, as well as novel vaccination platforms, e.g. outer membrane vesicles. This will be followed by assessing the efficacy of these candidates in a well-established tick-Borrelia-mouse model, aiming to find of a novel vaccine to prevent LB.

Specific tasks:

  1. Molecular cloning, expression and purification of proteins.
  2. Characterization of the role of these proteins in tick-host-pathogen interactions in vitro and in vivo.
  3. Testing different formulations and vaccination platforms to determine and improve immunogenicity.
  4. Assessing protection of promising candidates using optimal formulations and vaccination platforms in tick-Borrelia mouse models.
  5. Collaborating with established national and international partners and actively seeking new collaborations.

The Amsterdam UMC

The Amsterdam UMC, location AMC, houses the university hospital and the medical faculty of the University of Amsterdam, as well as several research institutes. Infectious Diseases represents one of the major research topics at the AMC, integrated in a multidisciplinary fashion at the Amsterdam Infection & Immunity Institute (AI&II).

This research will take place at the Center for Experimental and Molecular Medicine (CEMM).

The mission of CEMM is to perform high quality translational research, bridging fundamental research with preclinical and clinical investigations in the field of Oncology, Infectious Diseases, and Blood Coagulation & Inflammation (i.e. the research groups housed in CEMM). It is the ambition of CEMM to facilitate translational science in the broadest of terms, maintaining strong ties with clinical departments and providing an optimal infrastructure and multidisciplinary environment for the scientific flourish of our research groups. The number one goal is to produce high quality, translational and impactful research.

The Lyme team is a dynamic young and ambitious group within CEMM with multiple PhD students, post-docs, technicians, physicians and a variable number of graduate students. The candidate will be working closely together with one of the post-docs and our biotechnician.
