Male yawns are much more contagious than female yawns among chimpanzees

Male yawns are much more contagious than female yawns among chimpanzees


Behavioral biologists from Utrecht University and BPRC, studied the contagiousness of yawning among the chimpanzee population in Burgers’ Zoo in Arnhem, the Netherlands. They showed that, as for humans, also the yawning of chimpanzees is contagious. Above all, they showed that chimpanzee male yawns are far more contagious for their conspecifics than female yawns. The study was published in PLOS One.

Potent neutralization of HIV by a Llama antibody

Potent neutralization of HIV by a Llama antibody


Some people are infected with the Human Immunodeficiency Virus (HIV) but do not get clinical symptoms. In these people, antibodies which can neutralize a broad range of HIV isolates have been detected. The breadth of this activity is important since HIV has the capacity to rapidly produce new variants. So far, attempts to mimic nature in animal models, trying to induce antibodies with similar potency and breadth, have failed.

Testing a variant of AMA1 as vaccine in humans

Testing a variant of AMA1 as vaccine in humans


Apical Membrane Antigen 1 (AMA1) is an important protein of the malaria parasite. This protein is regarded as a major vaccine candidate, since immunization with AMA1 has offered protection against malaria in various animal models. Researchers of the BPRC have developed the technology to produce this protein in large quantities, providing the opportunity to test the activity of this protein in humans.

Unraveling the coupling between the malaria parasite and red blood cell

Unraveling the coupling between the malaria parasite and red blood cell


Malaria parasites enter red blood cells to multiply and subsequently invade new red blood cells. This causes the disease malaria. Apical Membrane Antigen-1 (AMA-1), a protein of the malaria parasite plays an important role in the process of red blood cell invasion. Antibodies directed against AMA-1 can block invasion of red blood cells and therebye prevent disease. Therefore this protein is recognised as an important vaccine candidate against malaria.

Immunogenetics at the BPRC: rhesus monkeys answer essential questions


Transplantation technologies have improved life expectancy and quality of life for a significant group of people. Current transplantation technologies are partly based on research that has been performed at the BPRC.

A new class of antimalarial drugs

A new class of antimalarial drugs


New drugs against malaria are urgently needed, since resistance against all currently available drugs has been shown. In the leading journal PNAS a new development is reported: a new generation of compounds has been discovered that can attack the parasite at two compartments.

A map of genetic exchange of DNA in chimpanzees

A map of genetic exchange of DNA in chimpanzees


Recombination is an important process in biology. During this process DNA of the parents is exchanged generating a unique combination of DNA in the children. In the absence of this process we would all be equal at DNA level. A natural selection takes place in which benificial combinations remain in the population.
