Evidence for Biochemically Distinct Forms o f IL - 1 BY PATRICIA CAMERON

The term interleukin 1 (IL-1) encompasses macrophage-derived polypeptide factors in man, mouse, and other animals, which stimulate murine thymocyte proliferation (1-3), and in addition activate various target cells involved in chronic inflammation (4-10). The IL-1 produced by the murine macrophage line, P388D1, has a low isoelectric point (pI) and exhibits micro-charge heterogeneity in the rang...

Cameron-Liebler line classes

New examples of Cameron-Liebler line classes in PG(3,q) are given with parameter 1 2 (q 2− 1). These examples have been constructed for many odd values of q using a computer search, by forming a union of line orbits from a cyclic collineation group acting on the space. While there are many equivalent characterizations of these objects, perhaps the most significant is that a set of lines L in PG...
