Human beings are the first time to follow the new crown virus mutation and "camouflage"!Lianying New Equipment allows new crown patients to all body T cell non -invasive visualization and helps vaccine research and development

Lianying Medical TOTAL-BODY PET-CT-CT UEXPLORER Explorer

Recently, the University of California's University of Davis (UC Davis) scientific research team announced a heavy result at the annual meeting of 2022 SNMMI (Nuclear Medicine and Molecular Image Association) in the field of nuclear medicine. Based on Lianying Medical Total-Body Pet-CT-CT-CT UEXPLORERER, human beings first observe the whole body of the human body through the naked eye and non-invasive manner, which will greatly help clinical vaccine and drug assessment.

In T cells, there is a cytotoxic T cell, also known as CD8+T cells. When it is attacked by the virus antigen and activated by vaccine, it can produce a powerful defense and resistance function to help the human body fight against the new coronary virus. This cell is in Play a key role in fighting new coronal virus, assessing immune response and vaccine response.

The world's first new crown whole body T cell PET appearance HD map, the dark parts (tonsils, spleen, and whole body bone marrow) in the figure reflect the large number of CD8+T cells

The new crown vaccine at this stage is mainly used to prevent viruses by activating human B cells (a type of human lymphocytes). However, the new crown virus is extremely cunning. When it evolved to the fifth -generation Omircong, its spiny protein (the key logo of antibody recognition of the new crown virus) mutations has been as many as 37. The successful escape from the hunting of antibodies so that the immune effect of activating B cells can not keep up with the speed of mutation in the new coronary virus.

The industry scientists have made their sights on T cells. Compared with B cells, T cells have a talent: no matter how the new coronal virus deforms, it can always know the perfect disguise of the new crown virus, thereby locking the "target enemy" and launching an attack.

However, the number of clinical assessment of CD8+T cells is very limited. In the past, only two means of blood analysis and puncture biopsy, because 95%of T cells in the human body exist in tissue instead of blood, so the routine of blood drawing is conventional The detection method is difficult to effectively monitor T cells; for patients, puncture biopsy is a traumatic examination method, and each time can only be selected for local tissue and organs for evaluation, and it cannot be observed throughout the body.

The UC Davis scientific research team based on Lianying Medical TOTAL-BODY PET-CT-CT-CT UEXPLORER Explorer research on patients with new coronary pneumonia rehabilitation period. 4D movies "to explore the response mechanism of the immune system to the virus.

Lianying Medical TOTAL-BODY PET-CT-CT UEXPLORER Explorer, as the "topic king" of the molecular imaging industry, has attracted much attention from its birth. The device is known as the "Hubble Telescope" inside the human body, which is nearly two meters long and can cover the body of the body for scanning. Since entering UC Davis in 2019, UC Davis ’s research team has gradually unveiled the mystery of the vast universe of molecular image precision medicine based on UEXPLORER explorers, showing the mysteries of more and more life to the world. The diagnosis of malignant tumors has achieved a series of academic achievements in the fields of research and development, integrated diagnosis and treatment, and published in "Journal of Nuclear Medicine" (American nuclear medicine) and "EUROPEAN JOURNAL Medicine and Molecular Imaging" (Europe "(Europe Nuclear medicine and radiology and radiology journals such as nuclear medicine and molecular imaging magazines) and "Radiology" (radiology magazine).

At present, the equipment has settled in a series of top domestic and foreign hospitals and research institutes such as Zhongshan Hospital, Henan Provincial People's Hospital, and Michigan State University. In the future Development, for the benefit of patients all over the world, open a brand new door for the mysteries of human beings.
