Our brain maps out our body to facilitate accurate motor control. For a century, the body map has been thought to have applied to all types of motor actions. Now, a research group has revealed that the body relies on multiple maps based on the choice of motor system.

Patients with epilepsy must take medicine to manage seizures. Even then, only 65% are able to control their symptoms, rendering invasive surgery the only cure. Now, a research group has investigated a new stimulation paradigm that could cultivate greater resistance to epilepsy.

Researchers at Kanazawa University report in Applied Physics Letters the design of an ultrafast amplitude detector for use in high-speed atomic force microscopy. The detector will enable the real-time recording of fast dynamical processes of biomolecules.

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.
Allergic reaction and immune tolerance mechanism

We have succeeded in establishing a mouse model that develops gastric cancer closely resembling advanced human gastric cancer. Using this model, we have discovered gastric cancer stem cells, i.e. Lgr5+ gastric cancer cells, essential for the development, maintenance, and metastasis of cancer. Our study provides an experimental system that enables detailed analysis of highly malignant gastric cancer and is expected to lead to the development of a breakthrough treatment for advanced human gastric cancer.

We have clarified at the molecular level the mechanism by which a microenvironment, a so-called niche that surrounds cancer cells, is formed in which stromal cells and immune cells are attracted at an initiation stage of breast cancer onset. A molecule called FRS2β is found to be critical for creating this microenvironment. The present finding is expected to be beneficial in prevention, diagnosis and treatment of cancers at the initiation stage.

Malfunctioning of the so-called Hippo signalling pathway within animal cells leads to irregular activity of proteins that regulate genes involved in cell proliferation. Researchers have identified a key step in the process of this aberration, opening the door to new therapeutics for cancers such as head-and-neck squamous cell carcinoma and lung adenocarcinoma.
