Thinking of doing your PhD in the Life Sciences? The International PhD Programme (IPP) Mainz is offering
talented, young scientists the chance to work on
cutting edge research projects within the open call on “Molecular Biomedicine & Ageing”. As an IPP PhD student, you will join a
community of exceptional scientists working on diverse topics ranging from how organisms age or how our DNA is repaired, to how epigenetics regulates cellular identity or neural memory.
PhD position: Dendritic cell bias in skin infection and cancer (m/f/d)
Activities and responsibilities
The research group of Johannes Mayer offers the following PhD project:
Type 2 immune responses play an important role in the defense against parasites, effective wound healing and protection against toxins. Type 2 immune responses have however also been associated with detrimental immunity such as allergy and the suppression and reprogramming of proinflammatory pathways. Type 2 associated immunity has also been described within the tumor microenvironment, leading to ineffective tumor killing. Within the skin many of these responses are constantly active, correlating with an enhanced risk of allergy development and opportunistic infections that benefit from a type 2 immune bias in this tissue. Dendritic cells play a fundamental role in the priming of T cell responses. Several lineages of dendritic cells have been described, which perform enhanced roles for certain immune responses, as cDC1 preferentially control CD8 T cell responses via cross-presentation, while cDC2 are specialized in driving different T helper cell responses by producing key molecules for their differentiation. For priming of type 2 immune responses, it is still debated if specific molecular signals for their differentiation are required or if Th2 programs develop in the absence of classical activation cytokines. Our own research has identified a unique population of dermal dendritic cells that promote enhanced type 2 immune responses within the skin. Upon activation by parasite antigens this subset of CD11b-low dermal DC2 rapidly migrates to the draining lymph nodes to activate T cells via antigen presentation, costimulatory marker expression and cytokine production.
PhD in dendritic cell bias in skin infection and cancer
In this PhD project we want to understand if skin-specific subsets of dermal DC are also involved in driving detrimental type 2 immunity in the models of skin cancer and opportunistic skin infection. Dendritic cell phenotypes will be assessed using different single-cell and omics approaches established in our lab and functionally validated in transgenic mouse models that have defects in dendritic cell differentiation.
Due to their rapid activation and low frequency in tissues, the study of dendritic cells is challenging. Therefore, this PhD requires a strong background in immunology, previous experience with complex phenotyping of immune cells by flow cytometry (10+ markers) and previous experience with murine models of inflammation or infection.
