IL-10-signalering Cytokiner er proteiner der produceres af (bl.a.) immunceller og virker på (bl.a.) immunceller (leukocytter/hvide blodlegemer) IL-10 er et cytokin, der nedregulerer immunrespons, startet af f.eks. en bakterie 12
8.6 Gene Expression and Regulation TEKS 5C, 6C, 6D, 6E KEY CONCEPT Gene expression is carefully regulated in both prokaryotic and eukaryotic cells.

Complexities of Gene Expression Cells have regulated, complex systems –Not all genes are expressed in every cell –Many genes are not expressed all of.
What is central dogma? From DNA to Protein All proteins consist of polypeptide chains –A linear sequence of amino acids Each chain corresponds to the nucleotide.
Nucleic acids store and transmit hereditary information Contain the following elements: C, H, N, O, P Two types of nucleic acids: 1.DNA 2.RNA.
Objective: to understand RNA and transcription and translation 12.3.
