insect immunity comprises behavioral, physical and innate immunity. in this study, innate immune response of the greater wax moth larvae, galleria mellonella against two species of entomopathogenic nematodes, heterorhabditis bacteriophora and steinernema feltiae,   as important biocontrol agents were studied. total haemocyte count in larvae injected with h. bacteriophora increased immediately. ...

objective: infectious microorganisms are major sources of illness and death worldwide, and the leading cause of death in neonates. effective vaccination of this age group is of particular importance. the lack of a response and greater susceptibility to tolerance are two major features that limit the effectiveness of vaccines in neonates. in this study we compare the cellular immune response gen...

Maltose binding protein (MBP) is often fused to a relevant protein to improve its yield and facilitate its purification, but MBP can also enhance the immunogenicity of the fused proteins. Recent data suggest that MBP may potentiate antigen-presenting functions in immunized animals by providing intrinsic maturation stimuli to dendritic cells through TLR4. The aim of this study was to examine if ...

BACKGROUND Chromoblastomycosis is a chronic fungal infection that affects skin and subcutaneous tissue. Lesions can be classified in tumorous, verrucous, cicatricial and plaque type. The cellular immune response in the severe form of the disease seems to correlate with a Th2 pattern of cytokines. The humoral immune response also seems to play a role. We intended to explore the populations of re...

Manipulative endoparasites can alter the behaviour and the physiology of their intermediate hosts in ways that increase the probability of successful transmission to the final host. This requires that the parasite is able to circumvent its host's immune defence. Successful immune evasion may depend on host-parasite coevolutionary history and the appearance of new hosts invading the local host p...

We present a Caputo fractional order mathematical model that describes the cellular infection of Hepatitis B virus and immune response body with Holling type II functional response. study existence unique positive solutions local global stability virus-free endemic equilibria. Finally, we numerical results using Adam-type predictor–corrector iterative scheme.

Recent evidence suggests that local immunoregulation may prevent rejection of the placenta by the mother. This local immunoregulation may also compromise the response to placental infection. Listeria monocytogenes infection in 121 pregnant mice and 1,050 fetoplacental units was examined and the kinetics of bacterial growth in various maternal and fetal tissues were determined. A subset of pregn...

Human T-lymphotrophic virus type 1 (HTLV-1) is a retrovirus that is thought to infect approximately 10-20 million people worldwide. The majority of infected individuals remain asymptomatic carriers lifelong. HTLV-1 is thought to cause both local and systemic inflammatory diseases. The most common inflammatory condition associated with HTLV-1 is HTLV-1 associated myelopathy/Tropical spastic para...
