The series of molecular signals initiated by androgen binding to its receptor, and ending with the regulation of a downstream cellular process, e.g. transcription.

The morphogenetic process in which a bud forms from the mammary placode. A mammary bud is bulb of epithelial cells that is distinct from the surrounding epidermis.

The progression of the nipple over time, from its formation to the mature structure. The nipple is a part of the mammary gland that protrudes from the surface ectoderm.

The orderly movement of epithelial cells within the mammary line that contributes to the formation of the mammary placode.

OBSOLETE. The transfer of information between living organisms.

Binding to a Toll-like 2 protein, a pattern recognition receptor that binds microbial pattern motifs to initiate an innate immune response.

Binding to a Toll-like protein, a pattern recognition receptor that binds pattern motifs from a variety of microbial sources to initiate an innate immune response.

The series of molecular signals initiated by a ligand binding to a toll-like receptor where the TIRAP/MAL adaptor mediates transduction of the signal. Toll-like receptors directly bind pattern motifs from a variety of microbial sources to initiate an innate immune response.

The series of molecular signals initiated by a ligand binding to a toll-like 2 receptor where the MyD88 adaptor molecule mediates transduction of the signal. Toll-like 2 receptors are pattern recognition receptors that bind microbial pattern motifs to initiate an innate immune response.

A toll-like receptor signaling pathway in which the MyD88 adaptor molecule mediates transduction of the signal. Toll-like receptors directly bind pattern motifs from a variety of microbial sources to initiate an innate immune response.

Binding to a Toll-like 4 protein, a pattern recognition receptor that binds bacterial lipopolysaccharide (LPS) to initiate an innate immune response.
