Any process involved in the maintenance of an internal steady state of iron ions at the level of a cell.

The chemical reactions and pathways resulting in the formation of hemoglobin, an oxygen carrying, conjugated protein containing four heme groups and globin.

The process in which a myeloid precursor cell acquires specializes features of an erythrocyte.

The stages of blood cell formation that take place within the embryo.

Any process that activates or increases the rate or extent of B cell proliferation.

A receptor-mediated endocytosis process that results in the movement of receptors from the plasma membrane to the inside of the cell. The process begins when cell surface receptors are monoubiquitinated following ligand-induced activation. Receptors are subsequently taken up into endocytic vesicles from where they are either targeted to the lysosome or vacuole for degradation or recycled back to the plasma membrane.

The directed movement of transferrin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that activates or increases the rate or extent of T cell proliferation.

The process of directing proteins towards the vacuole that contributes to protein catabolism via the multivesicular body (MVB) pathway.

Any process that activates or increases the frequency, rate or extent of isotype switching.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the fungal-type vacuole membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
