Human transplantation with allogeneic donor organs results in non-matching of MHC and differential presentation of T cell antigens. Here the authors show that in a lung transplanted SARS-CoV-2 infected patient T cell responses generated from the host may not be able to recognise infected cells within the graft and this may contribute to virus persistence.

We show that the fraction of proliferating CD4⁺ lymphocytes is similar in HIV-infected subjects in the early stage of disease and in HIV-negative subjects, whereas the fraction of proliferating CD8+ lymphocytes is increased 6.8-fold in HIV-infected subjects. After initiation of antiviral therapy, there is a late increase in proliferating CD4⁺ T cells associated with the restoration of CD4⁺ T-cell counts. These results provide strong support for the idea of limited CD4⁺ T-cell renewal in the early stage of HIV infection and indicate that after effective suppression of virus replication, the mechanisms of CD4⁺ T-cell production are still functional in early HIV infection.

There is increasing effort to improve the signal sensitivity and explore the hyperpolarization dynamics. Here the authors demonstrate the parahydrogen spin transfer dynamics in compounds containing ¹⁵N using SABRE hyperpolarization technique with different strengths of the magnetic field.

Measurements on a chiral magnet show that non-symmorphic symmetries enforce topological crossings exactly at the Fermi level in certain materials; these crossings can be controlled by an applied magnetic field.

Classical light sources are characterized by their intensity and coherence, whereas quantum light sources are described by photon correlations. Here, the authors provide a connection between the two for the case of superradiant emission from quantum dots in a nanolaser.

The central amygdala relies on inhibitory circuitry to encode fear memories, but how this information is acquired and expressed in these connections is unknown. Two new papers use a combination of cutting-edge technologies to reveal two distinct microcircuits within the central amygdala, one required for fear acquisition and the other critical for conditioned fear responses. Understanding this architecture provides a strong link between activity in a specific circuit and particular behavioural consequences.

Benzodiazepines, such as valium, are used both in clinics and for recreational purposes, but lead to addiction in some individuals. Addictive drugs increase the levels of dopamine and trigger synaptic adaptations in the mesolimbic reward system, but the neural basis for the addictive nature of benzodiazepines remains elusive. Here, they are shown to increase firing of dopamine neurons in the ventral tegmental area through GABA_A receptor activation in nearby interneurons.
