Latest Patents

Paul Payette holds a patent for "Protein tyrosine phosphate-1B (PTP-1B) deficient mice and uses thereof." This invention provides mice that have had their PTP-1B genes disrupted by targeted homologous recombination. The mice exhibit no detectable PTP-1B protein but appear physiologically normal. Notably, these mice have half the level of circulating insulin compared to their wild-type littermates when fed a normal diet. In glucose and insulin tolerance tests, they demonstrate increased insulin sensitivity. Furthermore, when subjected to a high-fat, high-carbohydrate diet, these mice show resistance to weight gain compared to their wild-type counterparts. The patent also includes methods for creating these mice and cell lines derived from them, as well as methods for identifying inhibitors of PTP-1B enzymatic activity.

Career Highlights

Throughout his career, Paul Payette has focused on innovative research that bridges genetics and metabolic health. His work has contributed to a deeper understanding of how genetic modifications can influence physiological responses, particularly in relation to insulin and weight management.

Collaborations

Paul has collaborated with notable colleagues such as Brian P. Kennedy and Michael Gresser. These partnerships have enhanced the scope and impact of his research, leading to advancements in the field.

Conclusion

Paul Payette is a distinguished inventor whose work in genetic research has paved the way for new insights into insulin sensitivity and metabolic health. His patent on PTP-1B deficient mice exemplifies his innovative approach to addressing complex biological questions.
