Interferon

Human interferons have been classified into 3 groups: alpha, beta, and gamma. Both alpha- and beta-IFNs, previously designated type I, are acid-stable, but they differ immunologically and in regard to some biologic and physiochemical properties. The IFNs produced by virus-stimulated leukocytes (leukocyte IFNs) are predominantly of the alpha type. Those produced by lymphoblastoid cells are about 90% alpha and 10% beta. Induced fibroblasts produce mainly or exclusively the beta type. The alpha- and beta-IFNs differ widely in amino acid sequence. The gamma or immune IFNs, which are produced by T lymphocytes in response to mitogens or to antigens to which they are sensitized, are acid-labile and serologically distinct from alpha- and beta-IFNs.

2.

Interferon

Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. [from MeSH]

3.

Infection

The invasion of an organism's body tissues by disease-causing agents and their multiplication, as well as the reaction by the host to these organisms and/or toxins that the organisms produce. [from NCI]

Infection caused by Listeria

A bacterial infection caused by Listeria monocytogenes. It occurs in newborns, elderly, and immunocompromised patients. The bacteria are transmitted through ingestion of contaminated food. Clinical manifestations include fever, muscle pain, respiratory distress, nausea, diarrhea, neck stiffness, irritability, seizures, and lethargy. [from NCI]

Concept ID:

Disease or Syndrome
5.

Colonization

The presence of microorganisms (not contamination) on a body surface, including the skin and mucosal surfaces (e.g., respiratory, gastrointestinal, and urogenital tracts). Colonization implies the lack of signs or symptoms of infection but often precedes infection. [from NCI]

Gram-Positive Bacterial Infections

Infections caused by bacteria that retain the crystal violet stain (positive) when treated by the gram-staining method. [from MeSH]

MedGen UID:

Concept ID:
C0085426

8.

Bacterial infection by site

An acute infectious disorder that is caused by gram positive or gram negative bacteria; representative examples include pneumococcal, streptococcal, salmonella, and meningeal infections. [from NCI]

MedGen UID:

Concept ID:
C0004623
Disease or Syndrome
9.

Down-regulation

A negative regulatory effect on physiological processes at the molecular, cellular, or systemic level. At the molecular level, the major regulatory sites include membrane receptors, genes (GENE EXPRESSION REGULATION), mRNAs (RNA, MESSENGER), and proteins. [from MeSH]
