Gamma interferon could aid fight against fungal infections

01.11.2007
Interferon, the “superhero” cure for viral infections, may be a strong weapon in the battle against fungal infections in immunocompromised patients, according to an article in the November issue of Microbiology Today.

Fungal infections (mycoses) were once seen as exotic diseases, but this is changing rapidly. Although rarely life-threatening in healthy patients, fungal infections are a major problem for the immunocompromised, including HIV patients and people receiving chemotherapy for cancer. Treatment is becoming difficult due to fungal resistance to the antifungal therapy, the variety of disease-causing fungi found and the toxic effects of conventional therapy.

Now, scientists believe gamma interferon, a protein molecule produced by human cells in response to infections, may help to fight fungal infections. “Immune cells called neutrophils are rapidly recruited to the site of infection and play an essential role in fungal killing,” say Drs. Javier Capilla, Karl Clemons and David Stevens, of Santa Clara Valley Medical Center, Stanford Medical School and the California Institute for Medical Research. “Gamma interferon enhances the mechanisms of these cells to make them more potent killers of fungi.”

Tests on many fungal infections, including blastomycosis, candidosis and aspergillosis have shown that gamma interferon has beneficial effects in terms of the reduction of the fungus in the organs and on animal survival. But according to Dr Stevens, interferon is not the only answer. “Therapy using gamma interferon alone has failed to clear the fungus completely from infected tissues but it has great potential to add to conventional therapy.”

“When gamma interferon was given to mice infected with Cryptococcus along with amphotericin B, a standard antifungal treatment, the rate of cure was significantly higher than using one therapy alone. We need to look at the route of administration, the frequency of dosing and the dosage given before we can determine fully the use of gamma interferon as an adjunctive therapy.”

There is still work to be done. “We explored the possibility of using gene therapy for delivering gamma interferon into the nervous system to combat fungal meningitis. Studies of this type suggest a potential clinical use for specific gamma interferon gene therapy in the future. Treatment with gamma-interferon offers a new additional approach to treatment and it provides a new approach to treating difficult diseases. However, clinical trials must document the benefit for patients” says Dr Stevens.

•Viruses and Interferon – 50 years on (page 160)
•Chemokines, receptors and virus infection (page 164)
•Gamma interferon – key, but not sufficient for protection against TB? (page 172)

•Comment: Microbiology – a degree of concern (page 200)

These are just some of the articles that appear, together with all the regular features and reports of Society activities.

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
