Scientists at the University of Pennsylvania’s School of Veterinary Medicine Shed New Light on the Evolution of Adaptive Immunity in Cold-Blooded Vertebrates

[December 1, 2023; Philadelphia, PA] – Upon infection or immunization, all jawed vertebrate species generate proteins called antibodies that bind and neutralize pathogens. Strong and long-lasting antibody responses in warm-blooded species such as mammals are produced in secondary lymphoid microstructures (SLMs) among which germinal centers (GCs) are the centerpiece.

Uncovering the role of skin microbiome and immune response in cutaneous leishmaniasis

Two new studies led by Phillip Scott of the School of Veterinary Medicine and Elizabeth Grice of the Perelman School of Medicine demonstrate how bacteria found in leishmaniasis skin lesions and an associated immune response drive disease burden and treatment failure—and suggest new possibilities for treatment of the parasitic disease.
