Molecular sites on or in some B-lymphocytes and macrophages that recognize and combine with COMPLEMENT 3B. The primary structure of these receptors reveal that they contain transmembrane and cytoplasmic domains, with their extracellular portion composed entirely of thirty short consensus repeats each having 60 to 70 amino acids.

A glycine-rich, heat-labile beta-glycoprotein found in blood. It is a proactivator of complement 3 in the alternate pathway of complement activation. Factor B is converted by Factor D to COMPLEMENT 3 CONVERTASE. EC 3.4.21.47.

Voltage-dependent cell membrane glycoproteins selectively permeable to calcium ions. They are categorized as L-, T-, N-, P-, Q-, and R-types based on the activation and inactivation kinetics, ion specificity, and sensitivity to drugs and toxins. The L- and T-types are present throughout the cardiovascular and central nervous systems and the N-, P-, Q-, & R-types are located in neuronal tissue.

A topical anti-infective agent effective against gram-negative and gram-positive bacteria. It is used for superficial wounds, burns, ulcers, and skin infections. Nitrofurazone has also been administered orally in the treatment of trypanosomiasis.

An antibiotic substance isolated from the actinomycete Streptomyces rimosus and used in a wide variety of clinical conditions.

Cell surface proteins that bind calcitonin gene-related peptide (CGRP) with high affinity and trigger intracellular changes which influence the behavior of cells. CGRP receptors are present in both the central nervous system and the periphery and are not the same as calcitonin receptors.

A topically used antibiotic from a strain of Pseudomonas fluorescens. It has shown excellent activity against gram-positive staphylococci and streptococci. The antibiotic is used primarily for the treatment of primary and secondary skin disorders, nasal infections, and wound healing.

A sulfuric acid dimer, formed by disulfide linkage. This compound has been used to prolong coagulation time and as an antidote in cyanide poisoning.

A pyranoquinolone derivative that inhibits activation of inflammatory cells which are associated with asthma, including eosinophils, neutrophils, macrophages, mast cells, monocytes, and platelets.
