Inherited human RelB deficiency impairs innate and adaptive immunity to infection.

Proc Natl Acad Sci U S A

September 2024

Laboratory of Human Genetics of Infectious Diseases, Necker Branch, INSERM UMR 1163, Paris 75015, France.

Article Synopsis
  • Two unrelated adults were found to have genetic mutations causing a deficiency in a protein called RelB, leading to impaired immune responses.
  • This deficiency affects their ability to produce certain immune cells and antibodies, resulting in low levels of important T and B cells and impaired immune function.
  • As a result, the patients have an increased risk of infections due to their weakened immune system, and they produce harmful autoantibodies against type I interferons even after receiving stem cell transplants.

Background: People with factor XI deficiency have lower rates of ischaemic stroke than the general population and infrequent spontaneous bleeding, suggesting that factor XI has a more important role in thrombosis than in haemostasis. Milvexian, an oral small-molecule inhibitor of activated factor XI, added to standard antiplatelet therapy, might reduce the risk of non-cardioembolic ischaemic stroke without increasing the risk of bleeding. We aimed to estimate the dose-response of milvexian for recurrent ischaemic cerebral events and major bleeding in patients with recent ischaemic stroke or transient ischaemic attack (TIA).

Article Synopsis
  • Scientists studied over 176,000 people to see how certain genes might protect against Parkinson's disease (PD) and Alzheimer's disease (AD).
  • They found that specific types of a gene called HLA could help reduce the risk of these diseases and lower harmful proteins in the brain.
  • This suggests that our immune system might help protect us from PD and AD, which could lead to new treatments in the future.

  • Antimicrobial resistance (AMR) is when bacteria become tough against medicines, and it's a big problem for people and animals around the world.
  • Although we check for AMR in hospitals and vet clinics, we're not paying enough attention to monitoring it in the environment, which is really important for understanding how it spreads.
  • To get better at monitoring AMR in the environment, we need to learn more about normal AMR levels, find high-risk areas, and figure out how much antibiotics are around that could create resistance.

5-HT6 Receptors Sex-Dependently Modulate Hippocampal Synaptic Activity through GABA Inhibition.

Biomolecules

April 2023

Department of Health, UNICAEN, INSERM, COMETE, CYCERON, FHU A2M2P, CHU Caen, Normandie Université, 14000 Caen, France.

The subtype 6 of the serotoninergic receptors (5-HT6Rs) is highly expressed in the hippocampus, and evidence indicates the beneficial effects of 5-HT6Rs blockade on short- and long-term memory in rodents. Nevertheless, the underlying functional mechanisms still need to be established. To this end, we performed electrophysiological extracellular recordings to assess the effects of the 5-HT6Rs antagonist SB-271046 on the synaptic activity and functional plasticity at the CA3/CA1 hippocampal connections of male and female mice slices.
