In a study recently published in the Journal of Extracellular Vesicles, researchers from Kanazawa University use high-speed microscopy to capture the dynamics of nanosized sacs released from cells.

Researchers at the Institute of Industrial Science at The University of Tokyo introduce a machine learning method to help predict past infection from receptor sequences of immune T-cells even when little data is available, which may help improve human health and our understanding of adaptive immunity

Innate immunity is activated when the pattern recognition receptors (PRRs) recognize pathogen-associated molecular patterns (PAMPs). We show that a liver-derived secretory protein LECT2, a hepatokine, binds to the HGF receptor MET, a proto-oncogene product, to suppress the proliferation signal of MET. LECT2 activates retinoic acid-inducible gene-I, enhancing antiviral and innate immune responses through MET. Thus, LECT2 is an anti-proliferative and immunoregulatory factor that could be a therapeutic target for viral infections and cancer.

A booster dose of the Pfizer–BioNTech vaccine (BNT162b2) against SARS-CoV-2 after an initial two doses of either the CoronaVac inactivated virus vaccine or Pfizer–BioNTech mRNA vaccine is shown to provide protection against the Omicron variant, in a pair of papers published in Nature Medicine.

By searching for the protein transglutaminase 1 (TGM1) among patients with various autoimmune skin diseases, researchers have successfully identified a separate disease that can be linked to autoimmunity against TGM1. This backward method demonstrates a new way of identifying autoantigens as markers for various diseases. By letting autoantigens point to the disease, diagnosis and treatment can be facilitated, according to the study now published in PNAS.

Scientists at Hokkaido University and Texas A&M University have identified a key mechanism used by the SARS-CoV-2 virus to evade host immune systems.

Researchers have revealed in an animal model that ImmuBalance, a fermented soybean product, is effective in suppressing airway inflammation caused by asthma. Results showed a decreased presence of eosinophils in bronchoalveolar lavage fluid, a decrease in mucus production in the bronchial epithelium, and a suppression of proteins that induce eosinophilic inflammation.

Researchers discover a link between an increase in protein Ba of the complement immune system and the eventual development of thrombotic microangiopathy in patients who have received an allogeneic hematopoietic stem cell transplantation.

Scientists have developed a rapid, highly accurate test to detect antibodies against the spike protein of SARS-CoV-2 in human serum, opening a new avenue for understanding the full extent of the pandemic and evaluating the effectiveness of vaccines.

Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients.

Maternal antibodies primed to react to specific allergens can cross the placenta, passing on transiently allergic reactions to offspring, according to new preclinical research from a collaborative study by the Agency for Science, Technology and Research, KK Women’s and Children’s Hospital, and Duke-NUS Medical School in Singapore. The finding hints at why infants exhibit allergies so early in life and suggests possible targets for intervention.

Scientists have succeeded in reducing levels of the bovine leukemia virus (BLV) in cows with severe infections by combining an immune checkpoint inhibitor and an enzyme inhibitor. The finding could be utilized to control other diseases in cattle, and perhaps in humans someday.

Giants in history

Husband and wife team, Kimishige (3 December 1925 – 6 July 2018) and Teruko Ishizaka (28 September 1926 – 4 June 2019) discovered the antibody class Immunoglobulin E (IgE) that triggers allergic reactions. They also discovered that IgE antibodies attach to white blood cells, known as mast cells, releasing histamine, which causes allergic reactions.
