Damage signals in the insect immune response
Insects and mammals share an ancient innate immune system comprising both humoral and cellular responses. The insect immune system consists of the fat body, which secretes effector molecules into the hemolymph and several classes of hemocytes, which reside in the hemolymph and of protective border epithelia. Key features of wound- and immune responses are shared between insect and mammalian imm...
متن کاملCellular Events in the Immune Response
Cell suspensions from the spleens of normal mice or mice injected with sheep erythrocytes were separated on a discontinous bovine serum albumin density gradient. Four bands or subpopulations were obtained and were assayed for antibody-forming cells, and for antigen-sensitive precursor cells. The antibody-forming cells were assayed by the hemolytic plaque assay and the antigen-sensitive precurso...
متن کاملEvaluation of Cellular Immune Response against Purified Antigen 85 in Patients with Tuberculosis
Background: Tuberculosis (TB) remains an important health problem throughout the world. Despite its significance in public health, mechanisms of protective immunity against Mycobacyerium Tuberculosis in humans have not yet been understood. Objective: To evaluate cell mediated immune response against purified Ag 85, PPD and Phytohemagglutinin (PHA) in patients with tuberculosis and healthy tuber...
متن کاملCellular basis of the immune response.
Lymphocytes, the cells competent to initiate immune responses, can be divided into two major groups: thymus-derived or T cells responsible for "cellular immunity" (e.g. delayed hypersensitivity reactions) and bursa (or bursa-equivalent) derived or B cells which produce immunoglobulin (antibody) molecules and are involved in "humoral immunity". "Accessory" cells, such as monocytes (or macrophage...
متن کاملHIV's evasion of the cellular immune response.
Despite a strong cytotoxic T-lymphocyte (CTL) response directed against viral antigens, untreated individuals infected with the human immunodeficiency virus (HIV-1) develop AIDS. We have found that primary T cells infected with HIV-1 downregulate surface MHC class I antigens and are resistant to lysis by HLA-A2-restricted CTL clones. In contrast, cells infected with an HIV-1 in which the nef ge...
