Phenotype, specificity and avidity of antitumour CD8 T cells in melanoma.

Nature 2021 Jul 21. Epub 2021 Jul 21.

Department of Medical Oncology, Dana-Farber Cancer Institute, Boston, MA, USA.

Interactions between T cell receptors (TCRs) and their cognate tumour antigens are central to antitumour immune responses; however, the relationship between phenotypic characteristics and TCR properties is not well elucidated. Here we show, by linking the antigenic specificity of TCRs and the cellular phenotype of melanoma-infiltrating lymphocytes at single-cell resolution, that tumour specificity shapes the expression state of intratumoural CD8 T cells. Non-tumour-reactive T cells were enriched for viral specificities and exhibited a non-exhausted memory phenotype, whereas melanoma-reactive lymphocytes predominantly displayed an exhausted state that encompassed diverse levels of differentiation but rarely acquired memory properties.

Sci Rep 2021 Jul 21;11(1):14857. Epub 2021 Jul 21.

Laboratório de Pesquisa em Malária, Instituto Oswaldo Cruz & Centro de Pesquisa, Diagnóstico e Treinamento em Malária (CPD-Mal) of Fundação Oswaldo Cruz (Fiocruz) and of Secretaria de Vigilância em Saúde (SVS), Ministério da Saúde, Fiocruz. Av. Brasil 4365, Manguinhos, Rio de Janeiro, RJ, CEP 2104-360, Brazil.

The immune system plays a role in the maintenance of healthy neurocognitive function. Different patterns of immune response triggered by distinct stimuli may affect nervous functions through regulatory or deregulatory signals, depending on the properties of the exogenous immunogens. Here, we investigate the effect of immune stimulation on cognitive-behavioural parameters in healthy mice and its impact on cognitive sequelae resulting from non-severe experimental malaria.

Favored outgroup can eliminate the ingroup reference effect.

Scand J Psychol 2021 Jul 21. Epub 2021 Jul 21.

School of Psychology, Shaanxi Normal University, Xi'an, China.

Studies have found that, consistent with the ingroup favoritism effect, the recollection of ingroup related information is better than that of outgroup related information. This study explores whether preferred outgroup can eliminate the ingroup reference effect. Using the university as the reference group, Experiment 1 was designed to verify the group reference effect when there was no outgroup favoritism, and Experiment 2 examined the impact of outgroup favoritism on the group-reference effect.

Single-neuron correlate of epilepsy-related cognitive deficits in visual recognition memory in right mesial temporal lobe.

Epilepsia 2021 Jul 21. Epub 2021 Jul 21.

Department of Neurosurgery, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

Objective: Impaired memory is a common comorbidity of refractory temporal lobe epilepsy (TLE) and often perceived by patients as more problematic than the seizures themselves. The objective of this study is to understand what the relationship of these behavioral impairments is to the underlying pathophysiology, as there are currently no treatments for these deficits, and it remains unknown what circuits are affected.

Methods: We recorded single neurons in the medial temporal lobes (MTLs) of 62 patients (37 with refractory TLE) who performed a visual recognition memory task to characterize the relationship between behavior, tuning, and anatomical location of memory selective and visually selective neurons.

Infants scan static and dynamic facial expressions differently.

Infancy 2021 Jul 20. Epub 2021 Jul 20.

School of Psychology, University of Kent, Canterbury, UK.

Despite being inherently dynamic phenomena, much of our understanding of how infants attend and scan facial expressions is based on static face stimuli. Here we investigate how six-, nine-, and twelve-month infants allocate their visual attention toward dynamic-interactive videos of the six basic emotional expressions, and compare their responses with static images of the same stimuli. We find infants show clear differences in how they attend and scan dynamic and static expressions, looking longer toward the dynamic-face and lower-face regions. Read More

Refinement of the spinal cord injury rat model and validation of its applicability as a model for memory loss and chronic pain.

Heliyon 2021 Jul 7;7(7):e07500. Epub 2021 Jul 7.

Department of Experimental Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.

Background: Laminectomy produces trauma in spinal cord injury (SCI) animal models resulting in impinging artefacts and welfare issues. Mechanizing laminectomy using a dental burr assisted (DBA) technique to reduce the impact of conventionally performed laminectomy on animal welfare without any alterations in the outcome of the model was previously demonstrated. However, further validation was necessary to establish it as an alternative in developing SCI rats as a model of chronic pain and memory loss. Read More

Memantine improves memory and hippocampal proliferation in adult male rats.

Folia Neuropathol 2021 ;59(2):143-151

Department of Anatomy and Histology, Faculty of Medicine, University of Jordan, Amman, Jordan.

Neurogenesis occurs during the embryological development of the brain. However, it is universally accepted that in all adult mammalian brains, there are two sites of high-density cell division: the subventricular zone of the lateral ventricles (SVZ) and the subgranular zone (SGZ) of the dentate gyrus of the hippocampal formation. Doxorubicin (DOX) is an anthracycline agent which results in cognitive deterioration and memory impairment, whereas memantine (MEM) is an NMDA receptor antagonist which is approved for the treatment of Alzheimer's dementia.

Detecting accelerated long-term forgetting: A problem and some solutions.

Cortex 2021 Jul 1;142:237-251. Epub 2021 Jul 1.

School of Psychology, University of Leeds, Leeds, UK.

While many memory disorders occur with normal rates of forgetting, an accelerated rate of long-term forgetting (ALF) may occur, sometimes in the absence of a learning deficit. Detecting ALF presents a problem as it is desirable that the learned material is re-tested after each of several delays. This may result in earlier retrievals confounding later tests, with evidence suggesting that both positive and negative interaction can occur between successive tests. Read More

Developmental prosopagnosics and super recognizers rely on the same facial features used by individuals with normal face recognition abilities for face identification.

Neuropsychologia 2021 Jul 17:107963. Epub 2021 Jul 17.

School of Psychological Sciences, Tel Aviv University, Tel Aviv, Israel; Sagol School of Neuroscience, Tel Aviv University, Tel Aviv, Israel. Electronic address:

Face recognition depends on the ability of the face processing system to extract facial features that define the identity of a face. In a recent study we discovered that altering a subset of facial features changed the identity of the face, indicating that they are critical for face identification. Changing another set of features did not change the identity of a face, indicating that they are not critical for face identification. Read More
