    The immune system does battle in the intestines to keep bacteria in check

    New research from Penn Vet demonstrates that Yersinia pseudotuberculosis, a relative of the bacterial pathogen that causes plague, triggers the body’s immune system to form lesions in the intestines called…

    Harnessing an innate protection against Ebola

    In their evolutionary battle for survival, viruses have developed strategies to spark and perpetuate infection. Once inside a host cell, the Ebola virus, for example, hijacks molecular pathways to replicate…

    How sex differences may influence lung injury

    Comparing lung cells from male and female mice, Penn Vet scientists found gene expression differences that may explain why older males are at a higher risk than females for worse…

    In the Galápagos, training community scientists to monitor water quality

    Both dense human populations and a plethora of wildlife can pose a challenge to marine and public health in the Galápagos Islands. With portable, user-friendly PCR technology, Penn faculty and…

    Regulating the regulators of the immune system

    Research led by Penn Vet scientists reveals a new layer of complexity with which the immune system finds a balance between controlling pathogens and protecting healthy tissue.

    Revising the lifecycle of an important human parasite

    Researchers from Dr. Boris Striepen’s lab tracked Cryptosporidium in real time, creating a new paradigm for how the widespread parasite reproduces in a host.

    COVID in a cat

    A report led by Penn Vet’s Dr. Elizabeth Lennon and colleagues has confirmed what is believed to be the first published account of the delta variant of SARS-CoV-2 in a house…
