    Lightbulb Histamine

    Hi, Sorry guys, another question for you.

    Which cells release histamine and other chemical messengers?

    Am I right to believe:

    histamine is released from H1 receptors?

    Receptors don't release anything! they respond to chemical messengers.


    Laura, you need to use google a bit more. The simple phrase "Which cells release histamine and other chemical messengers?" put into google gave a huge number of hits.

    Top of the list was this:

    histamine (biochemistry) -- Britannica Online Encyclopedia


    your answer is there if you read the entry.

    Histamine is mainly released by mast cells.......but also by basophils - which are a type of white blood cell.
