Program in Cellular and Molecular Medicine (PCMM)
The Program in Cellular and Molecular Medicine (PCMM), is a research program at Boston Children's Hospital (BCH) recognized worldwide for its discoveries that increase the body's ability to fight disease and to heal. The breakthroughs of PCMM scientists are greatly increasing our understanding of the influence of immune defense and inflammation on medical discovery, healthcare, and disease management. PCMM officially joined seven other interdisciplinary programs at Boston Children's Hospital in October 2012 with the goal of increasing collaborations and scientific synergies. Our investigators are academically affiliated with Harvard Medical School.
We pursue six (at least) primary areas of research:
- Adhesion molecules and inflammation
- Autoimmunity and allergy
- Genetics of immunodeficiency and cancer
- Immune defenses against infectious diseases, viruses, and tumors
- Stem Cells
- Structural Biology
Getting a grip on genetic loops
Announcements
Chromatin loops unlock antibody class switching
|
Researchers in the laboratory of Frederick Alt of the Howard Hughes Medical Institute and Program in Cellular and Molecular Medicine (PCMM) at Children's Hospital Boston continue their groundbreaking work at the nexus of genetics and immunology, specifically the response of antigen-activated B cells to the enormous variety of possible threats, including bacteria, viruses, and parasites. Two reports from the Alt Lab in Nature (the first in September 2019 and a second online on October 30, 2019 with a Nature “News and Views” covering both) present major advances in chromatin regulation, showing that two distinct types of antibody gene recombination, occurring at different developmental stages, both depend upon reeling long loops of chromatin past recombination centers to align substrate gene segments in the processes known as V(D)J recombination and class switch recombination (CSR). |
Fred Alt Received AAI-BioLegend Herzenberg Award
Congratulations to Dr. Frederick W. Alt for receiving the BioLegend Herzenberg Award from the American Association for Immunologists (AAI). Established to honor the memory of AAI member Leonard A. Herzenberg Ph.D., this award recognizes investigator who has made outstanding for outstanding contributions to the field of Immunology in the area of B cell biology.
