The cannabinoids are a group of chemicals that include marijuana. These compounds bind to and activate the body's cannabinoid receptors. There are two types of cannabinoid receptor: the peripheral cannabinoid receptor (CB2) which is predominantly found in immune cells, and the central cannabinoid receptor (CB1) which occurs in the central nervous system.
Recent studies have suggested that CB2 may be involved in a wide range of physiologic phenomena related to immunity, although research on this function is still at an early stage. Among the possible immunological roles for CB2 is an involvement in the initiation of white blood cell migration to sites of infection and inflammation.
In the Journal of Biological Chemistry study, which was featured as a "Paper of the Week", Yumi Tohyama and colleagues used an in vitro model of blood cell migration to study the involvement of CB2 in the recruitment white blood cells. They found that treating the blood cells with compounds that bind to CB2 suppresses the migration of the cells. When they examined the cells, they discovered that they had lost their ability to develop a front/rear polarity, which is something they need to effectively migrate to sites of infection and inflammation.
Because cannabinoids seem to suppress activated white blood cells, Tohyama believes they could have a potential use in the treatment of inflammatory diseases.
The Journal of Biological Chemistry's Papers of the Week is an online feature which highlights the top one percent of papers received by the journal. Brief summaries of the papers and explanations of why they were selected for this honor can be accessed directly from the home page of the Journal of Biological Chemistry online at www.jbc.org.
The American Society for Biochemistry and Molecular Biology (ASBMB) is a nonprofit scientific and educational organization with over 11,000 members in the United States and internationally. Most members teach and conduct research at colleges and universities. Others conduct research in various government laboratories, nonprofit research institutions, and industry.
Founded in 1906, the Society is based in Bethesda, Maryland, on the campus of the Federation of American Societies for Experimental Biology. The Society's primary purpose is to advance the sciences of biochemistry and molecular biology through its publications, the Journal of Biological Chemistry, the Journal of Lipid Research, Molecular and Cellular Proteomics, and Biochemistry and Molecular Biology Education, and the holding of scientific meetings.
