Researchers from Osaka University found that antibiotic-resistant bacteria are fatter and shorter than their antibiotic-sensitive parental strains, and that these morphological changes correlate with changes in the expression of genes related to energy metabolism and antibiotic resistance. A machine learning approach was able to distinguish between antibiotic-resistant and antibiotic-sensitive bacteria in the absence of drug treatment based on microscope images, suggesting that bioinformatics could be used to detect antibiotic resistance in patient samples.

A recent study from Osaka University reveals that intensive diabetes treatment can improve periodontal disease inflammation. Researchers found that two weeks of intensive diabetes treatment under hospitalization for patients with type 2 diabetes significantly improved not only blood sugar control but also PISA, an indicator of gum disease inflammation. Furthermore, the improvement in PISA was related to factors such as insulin secretion capacity and the severity of diabetes complications and comorbidities before diabetes treatment. These findings suggest that early intervention in diabetes is crucial for improving gum disease in diabetic patients.

Researchers from Osaka University found that T cells recognize neoself-antigens––abnormal, unfolded host proteins presented by major histocompatibility complex II (MHC-II) lacking the invariant chain––as non-self antigens, leading to the development of autoimmunity. Reactivation of Epstein–Barr virus, a known risk factor for lupus onset and exacerbation, increases the presentation of neoself-antigens by MHC-II, which could help explain the link between viral infection and autoimmune disease.

Giants in history
Japanese biochemist Akira Endo (1933 – 2024) discovered the first statin, called mevastatin, which lowered cholesterol levels in the blood by inhibiting a key enzyme in the cholesterol biosynthesis pathway. His work laid the foundation for the development of statins to help patients lower their blood cholesterol levels and reduce their risk of heart disease or stroke.

Michiaki Takahashi (17 February 1928 – 16 December 2013) was a Japanese virologist who developed the first chickenpox vaccine.
Toshiko Yuasa (11 December 1909 – 1 February 1980) was the first Japanese female physicist whose research on radioactivity shed light on beta decay – the process in which an atom emits a beta particle (electron) and turns into a different element.
Baron Kitasato Shibasaburo (29 January 1856 – 13 June 1931) was a Japanese physician and bacteriologist whose work led to a new understanding of preventing and treating tetanus, diphtheria and anthrax.
By isolating soil microorganisms and studying the compounds they produce, Satoshi Omura (born 1935) discovered almost 500 organic compounds with unique properties that were produced by these microorganisms, including many new antibiotics.
In 1915, pathologist Katsusaburo Yamagiwa and his research assistant Koichi Ichikawa became the first to prove that chronic exposure to chemicals can cause cancer.

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.
