Any process that decreases the frequency, rate or extent of the translocation, or flipping, of phospholipid molecules from one monolayer of a membrane bilayer to the opposite monolayer.

Any process that activates or increases the frequency, rate or extent of phosphatidylserine exposure on apoptotic cell surface.

Any process that increases the frequency, rate or extent of the translocation, or flipping, of phospholipid molecules from one monolayer of a membrane bilayer to the opposite monolayer.

The directed movement of an astrocyte guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

The directed movement of a helper T cell in response to an external stimulus.

The directed movement of a T-helper 17 cell in response to an external stimulus.

The process of regulating the proliferation and elimination of monocytes such that the total number of monocytes within a whole or part of an organism is stable over time in the absence of an outside stimulus.

The movement of a monocyte from the bone marrow to the blood stream.

The movement of a mononuclear cell within or between different tissues and organs of the body.

The switching of activated B cells from IgM biosynthesis to IgE biosynthesis, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and IgE constant region gene segments in the immunoglobulin heavy chain locus, that is dependent on the activity of interleukin 4 (IL-4).

The change in morphology and behavior of a memory T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific.

The directed movement of a T-helper 1 cell in response to an external stimulus.

The directed movement of a T-helper 2 cell in response to an external stimulus.

The series of molecular signals initiated by interleukin-12 binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription.

The series of molecular signals initiated by interleukin-15 binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription.

The directed movement of large protein complexes along microtubules from the cell body toward the tip of a cilium (also called flagellum), mediated by motor proteins.

The bidirectional movement of large protein complexes along microtubules within a cilium, mediated by motor proteins.

The directed movement of large protein complexes along microtubules from the tip of a cilium (also called flagellum) toward the cell body, mediated by motor proteins.

The multiplication or reproduction of common myeloid progenitor cells, resulting in the expansion of a cell population. A common myeloid progenitor cell is a progenitor cell committed to the myeloid lineage.

Binding to lysophosphatidic acid (LPA), a phospholipid derivative that acts as a potent mitogen due to its activation of high-affinity G protein-coupled receptors.
