Slow road to a synapse

A study led by Subhojit Roy reveals how certain proteins in neurons travel at a slower pace than others, assembling into larger complexes that move down the axon. The proposed model suggests a 'plume' of proteins, where complexes disassemble and reassemble as they progress, making the overall motion slow and coordinated.

Scientists favor needles over tablets for global vaccinations

Researchers at the Trudeau Institute discovered that cytokines can influence immune responses to subsequent infections and vaccination procedures. This knowledge provides a potential explanation for why chronic infections can alter immune responses to vaccines. Needle vaccinations may be more effective in regions where people are alrea...

Papaya extract thwarts growth of cancer cells in lab tests

Researchers at the University of Florida have found that papaya extract thwarts the growth of cancer cells in lab tests, boosting the production of key signaling molecules and suggesting possible therapeutic strategies. The extract did not show toxic effects on normal cells, consistent with reports from indigenous populations.

Antibodies attack immune proteins

Two studies published in Journal of Experimental Medicine reveal that patients with a rare autoimmune disease produce antibodies that bind and disarm cytokines, which fight airborne pathogens. These findings may help explain the recurring nature of these patients' yeast infections.

Dual role for immune cells in the brain

Researchers found that macrophages along the blood-brain barrier can either activate the brain's stress response machinery or prevent excessive inflammation. This discovery may pave the way for novel therapies for neurodegenerative diseases.

Scientists identify natural anti-cancer defenses

Researchers at the University of Montreal identified a novel molecular mechanism that prevents cancer by regulating the p53 gene. The SOCS1 molecule plays a crucial role in suppressing cancer-causing cytokine activity, offering potential new treatments for chronic inflammatory diseases and cancer prevention strategies.

Teasing apart T helper cells

A recent study published in the Journal of Experimental Medicine shows that IL-9 promotes a multiple sclerosis-like disease in mice. The research suggests that IL-9 production may be linked to the presence of TGF-beta rather than a specific Th cell subset, contradicting the theory of a unique 'Th9' cell subset.

Environmental factors instruct lineage choice of blood progenitor cells

Researchers at Helmholtz Munich used new bioimaging techniques to show that hematopoietic progenitor cells are instructed by cytokines, steering their lineage choice. This discovery confirms the influence of environmental factors on cell differentiation and has important implications for optimizing therapeutic stem cell applications.

Just in time for spring: Scientists find the cellular on and off switch for allergies and asthma

Researchers identified a previously unknown cellular switch that regulates both allergic and asthmatic responses in the body. This discovery suggests that at least some people with asthma and allergies have genes that prevent this switch from working properly, leading to medication development targets.

Monitoring immune responses in disease

A new method allows for the detection of multiple immune parameters from individual human cells, which may aid in diagnosing diseases such as type 1 diabetes. This breakthrough enables researchers to study rare blood cells and their role in autoimmune diseases, leading to potential novel biomarkers for therapy monitoring.

Slacker or sick?

A study by Temple University researchers found that nerve injuries caused by repetitive strain can lead to chronic pain and degenerative problems, with cytokines playing a key role. Cytokines may affect employees' psychosocial responses, leading to 'sick-worker' syndrome, characterized by slacking off work and low-grade depression.

Immunoprivilege has its disadvantages

Research findings indicate that viral infections can cause chronic vascular disease by establishing a protected niche within the elastic media of large arteries. This 'immunoprivilege' allows viruses to evade the immune system, leading to destructive arteritis and inflammation.
