Healthy T cells are the foundation of a balanced immune system. They can spring into action to fight off infections or cancer, but keep from becoming so activated that they hurt the very cells they re meant to protect, as is the case in autoimmune diseases.

SAN FRANCISCO, CA April 21, 2021 Not all cancer cells within a tumor are created equal; nor do all immune cells (or all liver or brain cells) in your body have the same job. Much of their function depends on their location. Now, researchers at Gladstone Institutes, UC San Francisco (UCSF), and UC Berkeley have developed a more efficient method than ever before to simultaneously map the specialized diversity and spatial location of individual cells within a tissue or a tumor.
The technique, called XYZeq, was described online this week in the journal
Science Advances. It involves segmenting a tissue into a microscopic grid before analyzing RNA from intact cells in each square of the grid, in order to gain a clear understanding of how each particular cell is functioning within its spatial location. This offers new insight into the organization of tissues and the interplay between different cell types during disease, including in cancers.
