Cleveland Clinic Researchers Discover New Bacterium that Causes Gut Immunodeficiency
Cleveland Clinic researchers have discovered a new bacterium that weakens the immune system in the gut, potentially contributing to certain inflammatory and infectious gut diseases.
The team identified the bacterium, Tomasiella immunophila (T. immunophila), which plays a key role in breaking down a crucial immune component of the gut’s multi-faceted protective immune barrier.
Identifying this bacterium is the first step to developing new treatments for a variety of inflammatory and infectious gut diseases.

‘Tipping The Balance’ Of Immune Cells from Bad to Good Reverses Multiple Sclerosis Symptoms in Mice
According to the federal government’s National Institute of Neurological Disorders and Stroke, nearly 3 million people worldwide — with almost a third in the United States — are living with multiple sclerosis (MS), a disabling neurological disease in which the body’s immune system mistakenly attacks nerves feeding information to the central nervous system (the brain and spinal cord). Although rarely fatal, MS can lead to long-term disabilities, and impair movement, muscle control, vision and cognition.

Plant virus plus immune cell-activating antibody clear colon cancer in mice, prevent recurrence
A new combination therapy to combat cancer could one day consist of a plant virus and an antibody that activates the immune system’s “natural killer” cells, shows a study by researchers at the University of California San Diego. In mouse models of colon cancer, the combination therapy eliminated all tumors and prevented their recurrence, which in turn resulted in 100% survival. The therapy also increased survival in mouse models of melanoma.

In a study published today in the Annals of Internal Medicine, Johns Hopkins Medicine researchers say they believe that, for the first time, there is evidence to show that three doses of vaccine increase antibody levels against SARS-CoV-2 — the virus that causes COVID 19 — more than the standard two-dose regimen for people who have received solid organ transplants.
Immune Response to SARS-CoV-2 in an Asymptomatic Pediatric Allergic Cohort
Abstract: Disease-specific COVID-19 pediatric comorbidity has not been studied effectively todate. Atopy and food anaphylaxis disease states require improved characterization of SARS-CoV-2 infection risk. To provide the first such characterization, we assessed serum samples of a highlyatopic, food anaphylactic, asymptomatic…
Organ Transplant Recipients Remain Vulnerable to Covid-19 Even After Second Vaccine Dose
In a study published today in the Journal of the American Medical Association (JAMA), Johns Hopkins Medicine researchers show that although two doses of a vaccine against SARS-CoV-2 — the virus that causes COVID 19 — confers some protection for people who have received solid organ transplants, it’s still not enough to enable them to dispense with masks, physical distancing and other safety measures.
No more needles?
Blood draws are no fun.They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too.Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19, or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis.

Coronavirus antibodies fall dramatically in first 3 months after mild cases of COVID-19
A study by UCLA researchers shows that in people with mild cases of COVID-19, antibodies against SARS-CoV-2 — the virus that causes the disease — drop sharply over the first three months after infection, decreasing by roughly half every 73 days. If sustained at that rate, the antibodies would disappear within about a year.

New Method Detects Toxin Exposure from Harmful Algal Blooms in Human Urine
A newly developed method can detect even low-dose human exposure to microcystins and nodularin in human urine. During harmful algal blooms (HABs), species of cyanobacteria release toxic peptides, including microcystins and nodularin into waterways, impacting wildlife and humans living in these marine environments. These findings are the first to report microcystin concentrations directly from exposed residents impacted by cyanobacteria in Florida, and is a critical step in developing and interpreting clinical diagnostic tests for HABs exposure worldwide.
