Rescue of follicle development after oocyte-induced ovary dysfunction and infertility in a model of POI.

The mechanisms and aetiology underlying the development of premature ovarian insufficiency (POI) are poorly understood. However, the oocyte clearly has a role as demonstrated by the Double Mutant (DM) mouse model where ovarian dysfunction (6 weeks) is followed by POI (3 months) due to oocyte-specific deletion of complex and hybrid N- and O-glycans. The ovaries of DM mice contain more primary follicles (3a stage) accompanied by fewer developing follicles, indicating a block in follicle development.

Host resistance against Candida alibcans infection in mice with adjuvant induced arthritis.

In mice and humans two distinct CD4+ helper T cells, known as Th1 and Th2 are identified. They are characterized by the different cytokine milleau they induce. The balance between Th1 and Th2 responses is thought to be decisive for the initiation and course of some autoimmune disorders, as well as for the outcome of infectious processes.
