Microcystins are a group of cyclic heptapeptide hepatotoxins produced by a number of cyanobacterial genera. The most notable of which, and namesake, is the widespread genus Microcystis. Structurally, all microcystins consist of the generalized structure cyclo(-D-Ala1-X2-D-MeAsp3-Y4-Adda5-D-Glu6-Mdha7-). X and Y are variable L-amino acids, D-MeAsp is D-erythro-ß-methylaspartic acid and Mdha is N-methyldehydroalanine. Adda is the cyanobacteria unique C20 ß-amino acid 3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-deca-4,6-dienoic acid. Substitutions of the variable L-amino acids at positions 2 and 4 give rise to at least 21 known primary microcystin analogs and alterations in the other constituent amino acids result in more than 90 reported mycrocystins to date.

FLT-3 Ligand is a growth factor that regulates proliferation of early hematopoietic cells. FLT-3 Ligand binds to cells expressing the tyrosine kinase receptor FLT-3. FLT-3 ligand by itself does not stimulate proliferation of early hematopoietic cells, but synergizes with other CSFs and interleukins to induce growth and differentiation. Unlike SCF, FLT-3 ligand exerts no activity on mast cells. Multiple isoforms of FLT-3 Ligand have been identified.

Cytokines for polarizing T cells into T regulatory cells. T regulatory cells (Tregs) are a subset of T cells that suppress immune function. They are characterized by the expression of CD4, CD25 and Foxp3 and are known to produce immunosuppressive cytokines TGF-β 1 and IL-10. Tregs can be cultured from naive CD4+ T cells by culturing them in the presence of IL-2 and TGF-β 1 with CD3 and CD28 stimulation. In some cases cells are also cultured with neutralizing antibodies to IL-4, IFNγ and IL-12 and/or retinoic acid.

LCN2 is iron-trafficking protein involved in multiple processes such as apoptosis, innate immunity and renal development. LCN2 binds iron through association with 2,5-dihydroxybenzoic acid (2,5-DHBA), a siderophore that shares structural similarities with bacterial enterobactin, and delivers or removes iron from the cell, depending on the context. LCN2 is involved in apoptosis due to interleukin-3 (IL3) deprivation: iron-loaded form increases intracellular iron concentration without promoting apoptosis, while iron-free form decreases intracellular iron levels, inducing expression of the proapoptotic protein BCL2L11/BIM, resulting in apoptosis. LCN2 is involved in innate immunity, possibly by sequestrating iron, leading to limit bacterial growth.
