There are two classifications of cells in the human body, namely, germ cells that are used to make sperm and eggs, and somatic cells making up every other cell in … Continue Reading New lung cell type identified.
Neurodegeneration in Alzheimer’s disease is thought to be caused by the abnormal behavior of amyloid-beta molecules, which are known to gather into tough fibril-like structures called amyloid plaques within patients’ … Continue Reading Human amyloid-beta shown to act as a powerful antibiotic in the brains of animal models.
Natural killer (NK) cells are bone marrow–derived granular lymphocytes that have a key role in immune defense against viral and bacterial infections and malignancies. NK cells are traditionally defined as … Continue Reading Study shows that natural killer cells have a memory.
A person’s genetic makeup plays a role in autoimmune diseases such as multiple sclerosis that develop when the body is attacked by its own immune system. However, little is known … Continue Reading Study maps gene variants to DNA regions that regulate immune cells.
A fundamental question in human immunodeficiency virus 1 (HIV-1) research is why the immune system is unable to contain the virus. Unlocking this key would provide a significant advance in … Continue Reading New study explains why HIV is not cleared by the immune system.
The innate immune system is hard-wired to protect people from infection. However, mutations in these protective genes can lead to uncontrolled inflammation, resulting in autoinflammatory disease. Autoinflammatory diseases are characterized … Continue Reading Precision medicine study identifies decades-old mysterious, rare and debilitating disease.
An innocent mistake made by a graduate student in a Northwestern Medicine lab (they accidentally used male mice instead of female mice during an experiment) has led scientists to an … Continue Reading Simple mistake made in study leads to sex bias breakthrough in multiple sclerosis.
Study identifies transporter proteins responsible for human’s placenta protective ability during pregnancy.
An important function of the human placenta is to protect the fetus from detrimental substances in maternal blood, such as glucocorticoids or toxins. Placental membrane-bound transporter proteins, known as multidrug … Continue Reading Study identifies transporter proteins responsible for human’s placenta protective ability during pregnancy.
Inflammatory processes occur in the brain in conjunction with stroke and neurological diseases such as Alzheimer’s and Parkinson’s disease. Researchers from Lund University, the Karolinska Institutet and the University of … Continue Reading New findings on microglial activation during neuroinflammation.
When it comes to skin infections, a healthy and robust immune response may depend greatly upon what lies beneath. In a new study published in the journal Science, researchers at … Continue Reading Scientists identify new immune response via human fat cells.
