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.

MET signaling plays a critical protective role in acetaminophen-induced acute liver failure

A new study has found that MET (hepatocyte growth factor receptor) signaling plays a critical protective role in acetaminophen-induced acute liver failure (ALF).

New prevention strategy can reduce deadly ovarian cancer risk by nearly 80%

A prevention strategy developed by Canadian researchers can reduce the risk of the most common and deadly form of ovarian cancer by nearly 80 per cent, according to a new study published today in JAMA Network Open by researchers at the University of British Columbia (UBC).

Blood gene signals reveal Parkinson’s risk years before diagnosis

Blood-based DNA repair and stress-response signals reveal early molecular changes in Parkinson's disease, aiding in potential early diagnosis and intervention.

Chlamydia pneumoniae found in the eye may aggravate Alzheimer’s disease

Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer’s disease, according to a study from Cedars-Sinai.

Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

Characteristic features of bone marrow metastasis from non-hematolymphoid malignancies

Bone marrow metastasis (BMM) from non-hematolymphoid malignancies with resultant cytopenia(s) can mimic primary hematolymphoid disorders. This study aimed to investigate the clinical and pathological characteristics of BMM from non-hematopoietic tumors.

Lab-grown corticospinal neurons offer new models for ALS and spinal injuries

Researchers have developed a way to grow a highly specialized subset of brain nerve cells that are involved in motor neuron disease and damaged in spinal injuries.

Study uncovers how the brain's 'memory replay' process is impaired in Alzheimer's disease

Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College London (UCL) scientists.

Combination therapy improves cognition in Alzheimer’s models

In recent years, research into cannabis and its main psychoactive ingredient, Δ⁹-tetrahydrocannabinol (THC), has unearthed medical benefits including anti-inflammatory and neuroprotective properties.

How DNA and life experiences leave distinct marks on the human immune system

Using single-cell epigenomic profiling of immune cells from 110 individuals, researchers show that genetic variation and environmental exposures shape the human immune system through distinct DNA methylation mechanisms. Genetic effects concentrate within gene bodies of memory cells, while environmental exposures primarily remodel regulatory regions in naive immune cells.

Antibody-producing plasma cells shape effectiveness of PD-1 immunotherapy

Scientists at the Icahn School of Medicine at Mount Sinai have identified an important immune response that helps explain why some cancer patients benefit from immunotherapy while others do not.

Immune system dysfunction may fuel progressive heart failure after heart attacks

When the heart's muscle is weakened or injured due to a heart attack, it can make it hard for the heart to pump enough blood to meet the body's needs.

New research initiative aims to develop retinal screening tool for Alzheimer's

The human eye may literally become a window revealing the earliest signals of Alzheimer's disease, thanks to a new federally funded research initiative at Oregon Health & Science University.

CTE should be recognized as new cause of dementia, study suggests

The largest study of its kind from the Boston University CTE Center reveals that chronic traumatic encephalopathy (CTE) should be recognized as a new cause of dementia.

Game-changing discovery reveals how viruses may trigger ALS development

A large, multidisciplinary team led by researchers from Texas A&M University has made a potentially game-changing discovery about the development of devastating motor neuron diseases like amyotrophic lateral sclerosis (ALS).

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

More iron, less damage: why chronic lung infections persist

Research shows that iron-rich conditions boost Pseudomonas aeruginosa growth and biofilm formation, yet reduce virulence, complicating chronic lung infections.

Evidence links gut microbiome changes to Alzheimer’s progression

Human studies consistently report gut microbiome differences in mild cognitive impairment and Alzheimer’s disease, but findings vary widely by cohort, methods, and taxa. Heterogeneity and limited longitudinal data prevent causal inference, highlighting the need for functional profiling and well-designed intervention trials.

Regular aerobic exercise slows a key marker of brain aging in midlife

Regular aerobic activity significantly reduces brain-PAD, indicating that exercise is crucial for maintaining brain health and reducing dementia risk.
