Secretory products of macrophages: twenty-five years on.
نویسنده
چکیده
No longer do scientists look down on macrophages as "garbage men" that act "nonspecifically." Last fall's Nobel Prizes honored two of the few scientists who studied macrophages three decades ago. Now perhaps thousands do, and the subtypes they describe reflect ongoing discoveries of macrophages' extraordinary plasticity.

Effect of Intra-Peritoneal Injection of Chitosan Nanoparticle Loaded with Leishmania major Excretory-Secretory Antigens on Macrophage Function in Exposure to Parasites in BALB/c Mice.
Background: Leishmania major (L.major) is a causative agent of leishmaniasis. The disease has now become a public health problem. Modulation of the immune responses to inhibit the infection or the proliferation of the parasite is an effective way to overcome the leishmaniosis. Leishmania parasite secretory-excretory antigens are responsible for immune system modulation; therefore, they are u...

Background and Objective: Leishmaniasis is a public health problem caused by different types of Leishmania. The induction of apoptosis in infected macrophages is one of the main mechanisms for the escape of the parasite from the immune system. Preventing apoptosis and enhancing the ability to kill macrophages can be effective in treating or controlling leishmaniasis. In this study, the effect ...
متن کاملIdentification of excretory-secretory products from larval stages of Ostertagia circumcincta cultured in vitro by SDS-PAGE and immunoblotting
Exsheathing fluid (EF) and excretory-secretory products (ES) of infective third-stage cultured larvae ofOstertagia circumcincta were analysed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE). Five and seven predominant proteins were found in the EF and ES products, respectively. Immunoblotting by sheep pre-infection serum did not react with any of the EF and ES proteins, b...
متن کاملEFFECT OF FIVE ALPHA DIHYDROTESTOSTERONE (5α-DHT) ON CYTOKINE PRODUCTION BY PERITONEAL MACROPHAGES OF NZB/BALBc MICE
One of the mechanisms involved in the regulation of the immune system by steroid hormones could be the monocytic-macrophage system. In this study the effect of the male hormone 5a-DHT on cytokine release by peritoneal macrophages (mΦ) of male and female NZB/BALBc mice was investigated. Macrophages from male mice activated with LPS produced a greater amount of IL-1β (21.8%) (p<0.05) and IL-...
متن کاملImmunisation of lambs with excretory secretory products of Oestrus ovis third instar larvae and subsequent experimental challenge.
Excretory-secretory products (ESP) of myiasis producing agents are involved in nutrition and development of larvae and are often immunogens. This study was carried out in order to define the antigenicity, the immunogenicity of Oestrus ovis ESP and the role of sheep immune response to ESP. Twenty-four six to eight month old female lambs were randomly allocated into two groups. The first one was ...
