Drug repositioning is becoming popular due to the development of resistance to almost all the recommended antimalarials. Pregabalin and gabapentin are chemical analogs of gamma-aminobutyric acid (GABA) approved for the treatment of epilepsy and neuropathic pain.
Malaria transmission-blocking vaccines (TBVs) aim to inhibit parasite fertilization or further development within the mosquito midgut. Because TBV-immunized individuals reduce the transmission of malaria parasites to mosquito vectors, TBVs could serve as a promising strategy to eliminate malaria.
Malaria is a global health problem leading to the death of 435,000 cases in tropical and sub-tropical zones. Spread and emergence of increasing resistance to the antimalarial drugs are the major challenges in the control of malaria. Therefore, searching for alternative antimalarial drugs is urgently needed, and combination treatment preferred as an approach to address this. This study aimed to evaluate in vivo antimalarial activity of zingerone (ZN), and its combination with dihydroartemisinin (DHA) against Plasmodium berghei infected mice.
The development of a blood-stage malaria vaccine has largely focused on the subunit approach. However, the limited success of this strategy, mainly due to antigenic polymorphism and the failure to maintain potent parasite-specific immune responses, indicates that other approaches must be considered. Whole parasite (WP) vaccines offer many advantages over sub-units; they represent every antigen on the organism, thus limiting the effects of antigenic polymorphism, and similarly they compensate for individual Immune-Response (Ir) gene-regulated non-responsiveness to any particular antigen. From a development perspective, they negate the need to identify and compare the relative efficacies of individual candidate antigens. WP vaccines induce protective immunity that is largely cell-mediated.
The immune modulating potential of IL-35 in multiple human disorders has been reported. Consequent upon the recognition of inflammatory cytokine activation and its preponderance for mediating pathology during malaria infection, the study aimed to characterize the expression and functional contribution(s) of IL-35 in Plasmodium berghei (strain ANKA) infected mice.
Tamoxifen is an oestrogen receptor modulator that is widely used for the treatment of early stage breast cancer and reduction of recurrences. Tamoxifen is also used as a powerful research tool for controlling gene expression in the context of the Cre/loxP site-specific recombination system in conditional mutant mice.
Sleeping sickness and malaria are parasitic diseases with overlapping geographical distributions in sub-Saharan Africa. We hypothesized that the immune response elicited by an infection with Trypanosoma brucei, the etiological agent of sleeping sickness, would inhibit a subsequent infection by Plasmodium, the malaria parasite, decreasing the severity of its associated pathology.
Cerebral malaria (CM) is the severe neurological complication causing acute non-traumatic encephalopathy in tropical countries.
