A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Study connects hyperglycemia and prolonged cloth mask use to COVID-19-associated mucormycosis risk

A new study conducted in India identifies the role of high blood sugar levels in predisposing patients to mucormycosis infection.

Drug combination could make curative surgery possible for some liver cancer patients

A combination of the kinase-inhibitor drug cabozantinib and the immunotherapy drug nivolumab can make curative surgery possible in some liver cancer patients who would normally not be considered surgery candidates.

Scientists uncover genetics involved in COVID-19 induced respiratory failure

A new genetic study from an international team of scientists has uncovered genes involved in severe coronavirus disease 2019 (COVID-19) illness.

Study shows inhalable nanocatchers can protect lung cells against SARS-CoV-2

Inhalable nanocatchers that contain hACE2 have been recently developed by a group of researchers, providing a plethora of potential benefits in comparison to existing treatments against COVID-19.

Nasal swabs reveal muted antiviral response in patients who developed severe COVID-19

Over the past 18 months, researchers have learned much about COVID-19 and its viral cause, SARS-CoV-2. They know how the virus enters the body, coming in through the nose and mouth and beginning its infection in the mucus layers of the nasal passageway.

Blunted antiviral responses in the nasopharynx may underlie severe COVID-19

The body's first encounter with SARS-CoV-2, the virus behind COVID-19, happens in the nose and throat, or nasopharynx. A new study in the journal Cell suggests that the first responses in this battleground help determine who will develop severe disease and who will get through with mild or no illness.

Clinical trials during a pandemic – lessons from COVID-19

In this interview, Dr. Benedicte Roquebert, Dr. Stephanie Haim-Boukobza and Dr. Souad Mehlal discuss how COVID-19 has resulted in new ways to think about clinical trials during a pandemic.

Cell-analysis method could pave the way for new vaccine strategies against tuberculosis

A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.

'Good cholesterol' protects the liver from inflammation and injury, study shows

The body's so-called good cholesterol may be even better than we realize. New research from Washington University School of Medicine in St. Louis suggests that one type of high-density lipoprotein (HDL) has a previously unknown role in protecting the liver from injury.

Human tissue xenografts in murine models for the study of SARS-CoV-2

Severe COVID-19 is associated with massive dysregulation of the host immune response, resulting in inflammation and the condition known as a cytokine storm. For the most part, however, the virus is barely noticeable or only mild among the young and healthy, suggesting that the route and intensity of an immune response could determine the severity of the disease.

Next-generation COVID-19 vaccine provides robust immunity against SARS-CoV-2 in mice

Researchers in Canada have developed an adenoviral vector-based vaccine against coronavirus disease 2019 (COVID-19) that induced robust immune protection against the ancestral strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in mice.

How SARS-CoV-2 infects the brain

While there is no official explanation on how SARS-CoV-2 travels to the brain, a new review published in the journal Fluids and Barriers of the CNS concluded that there is insufficient evidence on COVID-induced neurological problems coming from a direct invasion of SARS-CoV-2 into the brain.

RUDN University biologists discover the way how macrophages respond to inflammation

RUDN University biologists discovered the way how macrophages (the cells of the "first line" immune response) respond to inflammation and identified how the immune response depends on their origin.

Enzyme inhibitor boosts immune system to fight MRSA and other dangerous skin infections

In what turned out to be one of the most important accidents of all time, Scottish bacteriologist Alexander Fleming returned to his laboratory after a vacation in 1928 to find a clear zone surrounding a piece of mold that had infiltrated a petri dish full of Staphylococcus aureus (S. aureus), a common skin bacterium he was growing.

Salivary markers of oxidative stress during severe COVID-19

An interesting study from researchers at the University of Sharjah, Sharjah, United Arab Emirates, presents evidence that an elevated level of expression of oxidant molecules may be correlated with severe infection and lung injury.

New immunotherapy treatment for cancer patients is more effective and less dangerous

Cell toxicity during immunotherapy is a major limitation to cancer treatment.

How does dexamethasone therapy work in severe COVID-19?

The possible mechanisms that result in dexamethasone being an effective drug against severe SARS-CoV-2 infection are investigated in a new study. The paper’s authors advance the hypothesis that SARS-CoV-2 infection induces cell-specific insensitivity to glucocorticoids, possibly as an unintentional result of the viral replication cycle.

Specific lung cell exhibits immune properties and improves respiratory viral disease outcomes

Researchers at Children's Hospital of Philadelphia have discovered that a specific type of lung cell exhibits unconventional immune properties and may contribute to the outcome of respiratory viral infections.

Connective tissue protein promotes immune responses that fight bacterial infections

A connective tissue protein known to support the framework of organs also encourages immune responses that fight bacterial infections, while restraining responses that can be deadly in the condition called sepsis, a new study finds.

Could the activation of FcγRIII/CD16 by anti-spike SARS-CoV-2 antibodies independently determine COVID-19 severity?

A team of scientists from Germany recently investigated whether hyperactivation of immune receptors that recognize the Fc part of an IgG molecule (FcγR) can lead to immunopathologic changes in coronavirus disease 2019 (COVID-19) patients. They have observed that hyperactivation of FcγRIII (CD16) by proinflammatory IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can significantly contribute to COVID-19 related immunopathology.
