Human Immunology (Single Cell Genomics) Lab
Machine-translated · View original
The lab uses single-cell analysis to decode human immunity.

AboutAbout the lab
Studying human immunity one cell at a time.
Okuzaki Lab studies human immunology at the Immunology Frontier Research Center, with a focus on single-cell analysis.
During the COVID-19 pandemic, the lab took part as a member of "Team Osaka University," performing single-cell analysis of cells in the blood (peripheral blood mononuclear cells).
The lab also uses single-cell analysis to examine immune responses after vaccination and the host immune responses to viruses and bacteria.
It also puts effort into applying the technology to connect basic research and clinical practice.
Key terms
- Single-cell analysis
- An analytical method that examines cells one by one to read differences between individual cells.
- Peripheral blood mononuclear cells (PBMC)
- A group of immune-related cells in the blood, such as lymphocytes and monocytes.
- NK cells
- A type of immune cell. They have cytotoxic activity, damaging and eliminating target cells.

ResearchResearch themes
Okuzaki Lab's mission is to advance single-cell analysis and human immunology. Centered on single-cell analysis, the lab also focuses on technological applications that connect basic research with clinical practice.
*Illustrative imageSingle-cell analysis of COVID-19
During the COVID-19 pandemic, the lab performed single-cell analysis of peripheral blood mononuclear cells (PBMCs) as a member of Team Osaka University, contributing to publications in major journals including Nature.
*Illustrative imageAntibodies that react to both viruses and self-antigens
In collaboration with many professors, the lab discovered a special antibody, "PA-N-CoV1804," that reacts to both viral antigens and self-antigens. It is found specifically in plasmablasts that differentiate and proliferate after infection, and the lab has reported findings on antibody responses in COVID-19 patients.
*Illustrative imageImmune features of encephalitis after vaccination
In patients who developed encephalitis after COVID-19 vaccination, the lab found a distinct immune signature in the peripheral immune system after onset. This cell population was not detected in healthy individuals or during remission, and is a unique myeloid subset.
*Illustrative imageNK cells in recovery from severe COVID-19
The lab investigated how NK cells diversify and undergo adaptive differentiation during recovery from severe COVID-19. It found that immature NK cells increase after vaccination, whereas in the recovery phase, adaptive NK cells with strong cytotoxic activity are induced.
