The regulated release of interleukin 1 beta from a cell.

The series of events in which a lipopolysaccharide stimulus is received by a cell and converted into a molecular signal. Lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.

Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that activates or increases the frequency, rate, or extent of chemokine production.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

A multiprotein complex that consists of at least three proteins, CD14, TLR4, and MD-2, each of which is glycosylated and which functions as a lipopolysaccharide (LPS) receptor that primes the innate immune response against bacterial pathogens.

An invagination of the cell membrane formed by an actin dependent process during phagocytosis. Following internalization it is converted into a phagosome.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The external part of the cell wall and/or plasma membrane.
