Melatonin dampens fetal membrane inflammation linked to preterm birth

Melatonin reduced infection-related inflammation in human fetal membranes in an ex vivo model. The study suggests that this effect works partly through melatonin receptors and by suppressing the TLR4/MyD88/NF-κB pathway.

New vaccines successfully boost frontline immune cells against HIV

T-cells are the immune system's frontline defenders with a crucial role in controlling HIV. In a milestone clinical trial published in the Journal of Clinical Investigation, researchers with the UNC Institute for Global Health and Infectious Diseases (IGHID) at the UNC School of Medicine have demonstrated that new vaccines can significantly boost T cells targeting the most vulnerable, conserved regions of HIV-areas considered key to effective immune control.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.

Click chemistry advances precision oncology by merging imaging and therapyly

Conventional cancer treatments like chemotherapy often struggle with poor targeting, leading to severe systemic toxicity and drug resistance.

Aged immune cells may drive memory decline by releasing a brain-aging protein

A preclinical mouse study in Immunity suggests that aged circulating CD8+ T cells can disrupt hippocampal function and impair learning and memory. The findings point to granzyme K, a secreted factor linked to age-associated CD8+ T cells, as a potential target for restoring aspects of cognition in aging.

Engineered regulatory T cells offer a path toward immunosuppression-free transplants

Organ transplantation remains the cornerstone treatment for end-stage organ failure. While conventional broad-spectrum immunosuppression effectively controls acute rejection, it fails to address chronic rejection and carries long-term side effects including infection, malignancy, and metabolic disorders.

Lab-grown skin organoids provide new insights into blood vessel pathology

New research has shown that single blood vessel cells that appear in the earliest stages of lab-grown skin organoids have the ability to form complex microvascular networks that grow and mature over time.

Bioengineered chewing gum reduces cancer-linked oral microbes

Researchers led by Henry Daniell of the School of Dental Medicine have shown that extracts from bioengineered chewing gum reduce the levels of three microbes known to be associated with head and neck squamous cell cancer (HNSCC), paving the way for more effective and affordable therapies.

Study shows older lung recipients can achieve outcomes comparable to youth

Today at the International Society for Heart and Lung Transplantation (ISHLT) 46th Annual meeting and Scientific Sessions, transplant specialists Brian Keller, MD, PhD, and Thomas Egan, MD debated an ethically fraught question: How old is too old for a lung transplant?

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

Non-clinical safety assessment crucial for CRISPR-based gene therapies

The rapid evolution of CRISPR/Cas genome editing has redefined the possibilities of cellular and gene therapy, enabling precise correction, disruption, and regulation of disease-associated genes.

Wireless ureteral stent sleeve enables early detection of hydronephrosis

Ureteral stents are widely used to relieve obstruction and protect kidney function, but they can also become blocked, triggering hydronephrosis and prolonged elevation of intrarenal pressure that may impair renal function.

Parasites trigger a gut-to-brain signal that cuts food intake during infection

Researchers found that intestinal tuft cells signal to crypt enterochromaffin cells by releasing acetylcholine, triggering serotonin release and activating a gut-to-brain vagal pathway during type 2 inflammation. This sustained signalling, rather than the initial acute response, was linked to reduced food intake in mouse models of parasitic infection.

Microfluidic chips enable realistic modeling of tumor immune environments

The challenge is that the tumor immune microenvironment is not a static backdrop but a constantly shifting ecosystem shaped by cancer cells, immune cells, stromal cells, cytokines, and physical barriers.
