Crohn’s disease (CD), one of the major forms of Inflammatory Bowel Disease, is a chronic relapsing intestinal disorder that affects millions of people globally. The cause of CD is unknown, but it is thought to result from a dysregulated immune response against environmental factors, including intestinal microbes, in genetically susceptible hosts.

The critical role that the intestinal microorganisms, collectively known as the gut microbiota, plays in the pathogenesis of CD has been investigated over the past two decades. Given the importance of the gut microbiota in triggering CD, the development of therapeutic approaches that target disease-causing intestinal microbes may provide a unique approach to the treatment of this disease [...]

A study from clinicians and researchers at the University of Michigan Rogel Cancer Center, U-M Department of Pathology and the Michigan Center for Translational Pathology reveals findings from over 800 clinical assays performed for kidney patients with MiTF family gene mutations.

After several decades of hard work by many scientists at the University of Michigan Medical School and elsewhere, an antibody (anti-C5a) has just been approved by the US FDA for treatment of humans who are septic and have developed lung infections with COVID-19, resulting in severe pulmonary dysfunction requiring external lung support. The antibody, anti-C5a, was originally developed in the Dr. Peter Ward laboratory in the early 2000s. The mAb was shown to dramatically reduce lung infections in polymicrobial sepsis in mice. 

A recently published research study led by Drs. Sem Phan and Tianju Liu from the Department of Pathology reported new findings that could help scientists predict disease progression and suggest a new immunotherapy target for the treatment of IPF and other fibrotic lung diseases.

These findings uncovered a new role for the immune checkpoint marker (B7-H3) in lung fibrosis that can potentially serve as a novel target for immunotherapy to slow down or abort the progression of lung fibrosis in patients with IPF and other chronic lung fibrotic diseases. In addition, sB7H3 levels in the plasma could serve as a potential marker to predict how quickly the disease progresses in patients and assess responsiveness to therapy, allowing for more informed treatment decisions.

Researchers from the Department of Pathology recently published a fascinating study into clinician’s perspectives on integrating pathologists into the patient’s care team in the form of pathology explanation clinics (PECs) [1]. Clinicians were asked, “How interested would you be in having your patient meet with a pathologist to discuss their pathology report and see their tissue under the microscope?”

As the SARS-CoV-2 virus continues to mutate over time and new booster vaccines become available, the question arises, are the multivalent boosters more effective at improving immune response than the monovalent vaccines with which we began? This question was addressed by a multi-site group from Columbia University Vagelos College of Physicians and Surgeons (New York) and from the University of Michigan Medical School Department of Pathology. Drs. Riccardo Valdez, Carmen Gherasim, and Aubree Gordon represented the Immunity Associated with SARS-CoV-2 (IASO) research team at U-M[...]

One of the most fascinating aspects of a career in cancer research is that one never knows when or where the next great discovery will occur. This was true of a recent breakthrough discovery made by the Dr. Russell Ryan laboratory at the University of Michigan Medical School. They were shocked to find that active regulatory elements in B-ALL contained not only typical protein binding sequences but also simple repeats of the sequence “GGAA”, usually considered a form of “junk DNA” with no regulatory function [...]

Members of the University of Michigan Department of Pathology and Michigan Center for Translational Pathology, in collaboration with the Clinical Proteomic Tumor Analysis Consortium, recently published a large study on clear cell renal cell carcinomas (ccRCCs), which represent about 75% of the RCC cases and account for the most RCC-associated deaths. This study set out to create a comprehensive profile of ccRCC, combining histologic and molecular profiles. By analyzing both the microscopic cell structures and the genetic makeup of the cells, these researchers discovered significant intratumoral heterogeneity in 90% of ccRCCs. This indicates that ccRCCs originate from multiple tumor cell lines, called tumor subclones, that may become metastatic and could independently influence response to therapies. Through this study, the team was able to molecularly stratify aggressive histopathic subtypes, which may lead to more effective treatment strategies for patients and improved survival.

For many of us, the idea of having blood drawn can be an unnerving thought. The use of needles and the sight of blood itself is not something we look forward to.

These cells are strategically distributed in peripheral tissues to provide important innate immunity to fight pathogens such as pathogenic viruses and bacteria.
