How immune cells “sniff out” pathogens

Researchers from the University of Bonn have developed a new method to study immune receptors using a label-free biosensor assay. This approach allows for the detection of specific chemical signals that activate Toll-like receptors (TLRs), which are found on the surface of immune cells and play a crucial role in detecting infections.

Brain changes: The lingering effects of COVID-19

Research shows COVID-19 can cause long-term changes to brain function through inflammation, affecting mood, concentration, and cognitive abilities in both young and old patients. Millions are potentially affected by this condition, also known as Long COVID.

How immune cells switch to attack mode

Macrophages change their metabolism drastically after coming into contact with bacteria, triggering an inflammatory response. This process involves the activation of Toll-like receptors, which leads to histone acetylation and changes in gene expression.

Lipid that aids normal skin turnover may help psoriasis

Researchers have discovered a lipid called phosphatidylglycerol (PG) that may help restore healthy skin turnover in people with psoriasis. PG reduced inflammation and raised skin lesions when applied topically to a mouse model of psoriasis, suggesting it could be a new treatment option.

Scientists work to dissolve the NETs that worsen TBI damage

Researchers have found evidence that dissolving NETs can reduce swelling and improve blood flow after traumatic brain injuries. A drug called DNase, which is currently used to thin out lung mucus in cystic fibrosis, appears to dissolve NETs and has shown promise in reducing swelling and improving recovery.

Autoimmune disease discovery could spark new treatments

Researchers have discovered a potent drug-like compound that inhibits Toll-like receptor 8, a key player in autoimmune diseases. The compound, CU-CPT8m, exerts potent anti-inflammatory effects on tissue, offering a potential breakthrough for treating rheumatoid arthritis and other autoimmune conditions.

Herpesviruses undercover

Scientists at HZI have shown that herpesviruses like KSHV and MHV68 modulate the TLR-induced proinflammatory cytokine response, allowing them to remain within the body for a long time. The researchers discovered that the virus actively prevents activation of the innate immune system through Toll-like receptors.

The pathway to asthma winds through toll-like receptor 4

Researchers found that toll-like receptor 4 is activated by fibrinogen cleavage products, which are generated by proteinase enzymes. This activation leads to the production of pro-inflammatory cytokines and the recruitment of immune cells to the airways, resulting in asthma-like symptoms.

Rat hippocampal neurons: An executor of neuroinflammation

Recent research reveals that Toll-like receptor 4 expressed in cerebral cortical neurons stimulates inflammatory pathways, suggesting that neurons may be both passive victims and activators of neuroinflammation. Lipopolysaccharide triggers the Toll-like receptor 4/nuclear factor-κB pathway, leading to neuroinflammatory responses.

Toll-like receptors play role in brain damage in newborns

New research reveals that Toll-like receptors play a major role in brain damage risk for newborns, contributing to conditions like cerebral palsy and epilepsy. The discovery could lead to more effective treatment strategies, such as blocking special TLRs to reduce brain damage following hypoxia.

Hopkins-led team solves failed vaccine mystery

Researchers discovered that a 1966 RSV vaccine's defective antibodies failed to bind to the real virus, leading to severe disease. New findings could lead to the development of safer and more effective vaccines for RSV and other respiratory viruses.

How do Lactobacilli treat Helicobacter pylori-related diseases?

Research shows Lactobacillus bulgaricus can prevent H. pylori lipopolysaccharide-activated TLR4 pathway, reducing IL-8 production and promoting gastric epithelial cell survival. The study suggests a novel relationship between probiotics and pathogenic bacteria in regulating inflammatory responses.

Arteries from distinct regions of the body have unique immune functions

Researchers at Emory University School of Medicine discovered that human arteries play distinct roles in the immune system depending on their anatomical location. Different types of arterial samples had varying Toll-like receptor gene expressions, which may explain why certain vascular diseases affect specific parts of the body.

Researchers learn why immune system's watch dogs howl

New research led by Brown University immunologist Wen-Ming Chu has uncovered a direct interaction between high-mobility group box 1 protein and toll-like receptor 9, triggering the immune response. The discovery could lead to the development of new vaccines and treatments for diseases such as cancer, asthma, and allergies.
