Pathology News and Research

RSS

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called General pathology. Medical pathology is divided in two main branches, Anatomical pathology and Clinical pathology. Veterinary pathology is concerned with animal disease whereas Phytopathology is the study of plant diseases.

Groundbreaking movement span framework redefines how we measure aging

Longstanding aging metrics have focused on how long people live and how long they live free of chronic disease, but both overlook a core component of daily well-being: the ability to move through the world with ease and confidence.

C. diff uses dual-threat sensing system to survive gut stress

The pathogen Clostridioides difficile (C. diff) - a leading cause of hospital-acquired infections - must contend with a variety of threats inside the harsh environment of the gut to survive and grow.

New blood screening algorithm reduces unnecessary Alzheimer's PET scans

A new blood-based screening algorithm dramatically reduced the number of unnecessary PET scans needed to recruit patients at risk of Alzheimer's disease for a clinical trial, according to research from scientists at the Keck School of Medicine of USC published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association.

Retinal immune cell gateway may unlock targeted uveitis treatments

As part of an effort to understand the molecules and mechanisms that regulate transendothelial migration in different vascular beds of the body, researchers focused on the blood vessels of the retina, part of the blood-brain barrier.

Physics-guided framework doubles digital pathology resolution for cancer screening

Digital pathology relies on high-resolution imaging for accurate cancer diagnosis, yet high-magnification systems remain slow and costly for large-scale screening.

GLP-1 drugs looked promising for depression. The evidence tells a more complicated story

A systematic review of 43 studies found highly heterogeneous results for GLP-1 receptor agonists across animal models and human research assessing depression-, anxiety-, and stress-related outcomes. No study directly tested these drugs as a treatment for PTSD, and the available evidence does not currently support their use for depression or PTSD, although people with metabolic dysfunction may warrant further investigation.

Elusive stem cells offer clues to treat lumbar spinal stenosis

Researchers at Weill Cornell Medicine and Hospital for Special Surgery have discovered the stem cells—unspecialized cells that can develop into specific cell types—that give rise to the body's tendons and ligaments, the tissues connecting muscles and bones.

Scientists traced a hidden immune route that may worsen tau-linked brain damage

In a mouse model of tauopathy, conventional type 1 dendritic cells (cDC1s) cross-presented brain-derived antigens in deep cervical lymph nodes, priming CD8+ T cells that accumulated in the brain and promoted neurodegeneration. Disrupting cDC1s or their cross-presentation activity reduced CD8+ T-cell infiltration and protected against neuronal loss, while human primary tauopathy samples also showed increased brain CD8+ T cells, although cDC1 involvement in humans remains unconfirmed.

Mitochondrial stress triggers long-term protection against heart damage

Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do so much more-including acting as signaling hubs.

What your gut microbes may have to do with how your brain ages

This review examines how diet-driven changes in the gut microbiota and microbial metabolites may influence cognitive aging through immune, metabolic, neural, endocrine, and barrier-related pathways. It highlights SCFAs, tryptophan-derived metabolites, and bile acids as key signaling mediators while emphasizing that much of the mechanistic evidence remains preclinical and human evidence is largely associative.

Cancer-fighting T cells need small amounts of ROS to attack tumors, study finds

New research reveals a promising new target for treating cancer by harnessing a type of molecule previously thought to do more harm than good.

Cancer drug eliminates HIV-infected cells in animal model study

Emory University researchers have provided the first proof-of-concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved medication for cancer.

Two scientists win Horwitz Prize for Rett syndrome breakthrough

Columbia University will award the 2026 Louisa Gross Horwitz Prize to Adrian Bird and Huda Zoghbi for their pioneering work on epigenetic regulation in the nervous system and its role in human neurological disease, particularly Rett syndrome.

Host-targeting drugs offer new way to fight flu resistance

A drug that targets the host rather than the virus could get around the problem of anti-viral resistance. Every year, hundreds of thousands of people die of seasonal influenza, caused by infection with influenza A and B viruses.

Estrogen hormone combination may help relieve menopausal brain fog

Many women going through menopause report struggling with memory lapses, trouble concentrating and slower thinking, a set of symptoms often described as "brain fog."

AI tools map tumor architecture to predict treatment response

Spatial transcriptomics is a powerful tool to create a detailed map of not just how genes are expressed in a piece of tissue, but also where genetic activity takes place in different cells and locations within the tissue.

Milvexian fails to reduce cardiovascular events after acute coronary syndrome

Milvexian did not reduce major adverse cardiovascular events compared with placebo after a recent acute coronary syndrome and there was no increase in intracranial or fatal bleeding.

Primate-specific DNA change reveals a new link to dementia-related neurodegeneration

Brain diseases, including dementia, have long been studied using experimental animals such as mice. However, differences between the human and animal genomes have raised concerns that some disease mechanisms may not be fully explained by conventional animal models.
