Effect of group size and escape enrichment on reproductive performance of breeding does in part-time group housing Ghent University Research Institute for Agriculture, Fisheries and Food
Societal demands for group housing of social farm animals such as rabbits are increasing due to animal welfare concerns. When breeding does are housed in groups, maternal protective behaviour negatively affects the reproductive performance of the does. In part-time group housing, does are housed in single-litter cages starting shortly before parturition until the first part of lactation and then group housed for the second part after their ...
A decrease in peripheral thyroid hormone conversion efficiency in patients treated with immune checkpoint inhibitors and L-T3 as a possible alternative therapeutic escape option KU Leuven University of Antwerp
Hypothyroidism is a frequently occurring side effect in patients under treatment with immune checkpoint inhibitors (ICIs). Actually, the origin of hypothyroidism with ICI use is classified as a primary (thyroid) or as secondary/tertiary hypothyroidism (hypothalamus-pituitary). Treatment consists of levothyroxine (L-T4) substitution. Recently, we were rarely confronted with a clinically overt hypothyroidism in three patients under treatment with ...
Shedding of bevacizumab in tumour cells-derived extracellular vesicles as a new therapeutic escape mechanism in glioblastoma KU Leuven
Glioblastoma (GBM) is the most aggressive type of primary brain tumours. Anti-angiogenic therapies (AAT), such as bevacizumab, have been developed to target the tumour blood supply. However, GBM presents mechanisms of escape from AAT activity, including a speculated direct effect of AAT on GBM cells. Furthermore, bevacizumab can alter the intercellular communication of GBM cells with their direct microenvironment. Extracellular vesicles (EVs) ...
Natural killer cell immune escape in acute myeloid leukemia University of Antwerp
As central players of the innate immune system, natural killer (NK) cells can exert direct and indirect anti-tumor effects via their cytotoxic and immune regulatory capacities, pivotal in the induction of an effective adaptive anti-tumor immune response. Hence, NK cells are considered to be important in the immune surveillance of cancer. In acute myeloid leukemia (AML) patients, however, significantly impaired NK cell functions can facilitate ...
Escape of tick-borne flavivirus from 2’-C-methylated nucleoside antivirals is mediated by a single conservative mutation in NS5 that has a dramatic effect on viral fitness KU Leuven
Tick-borne encephalitis virus (TBEV) causes a severe and potentially fatal neuroinfection in humans. Despite its high medical relevance, no specific antiviral therapy is currently available. Here we demonstrate that treatment with a nucleoside analog, 7-deaza-2' -C-methyladenosine (7-deaza-2' -CMA), substantially improved disease outcome, increased survival, and reduced signs of neuroinfection and viral titers in the brains of mice infected with ...
Sequence evolution and escape from specific immune pressure of an HIV-1 Rev epitope with extensive sequence similarity to human nucleolar protein 6. Vrije Universiteit Brussel
Antigen-specific immunity is crucially important for containing viral replication in human immunodeficiency virus (HIV)-1-infected hosts. Several epitopes have been predicted for the early expressed HIV-1 proteins Tat and Rev, but few have been studied in detail. We characterized the human leukocyte antigen (HLA)-B44-restricted Rev epitope EELLKTVRL (EL9) in an HIV-1-infected subject treated with antiretroviral therapy. Interestingly, a high ...
Vaccination against trypanosomiasis : can it be done or is the trypanosome truly the ultimate immune destroyer and escape artist? Vrije Universiteit Brussel
To date, human African trypanosomiasis (HAT) still threatens millions of people throughout sub-Sahara Africa, and new approaches to disease prevention and treatment remain a priority. It is commonly accepted that HAT is fatal unless treatment is provided. However, despite the well-described general symptoms of disease progression during distinct stages of the infection, leading to encephalitic complications, coma and death, a substantial body of ...

JAK Mutations as Escape Mechanisms to Anti-PD-1 Therapy Vrije Universiteit Brussel
JAK mutations could be one of the primary escape mechanisms to anti-PD-1/PD-L1 immunotherapy via impaired IFNγ signaling in cancer cells and could be used to identify patients unlikely to benefit from these treatments.
