Peripheral HLA-G/ILT-2 immune checkpoint axis in acute and convalescent COVID-19 patients.

The immunosuppressive non-classical human leukocyte antigen-G (HLA-G) can elicits pro-viral activities by down-modulating immune responses. We analysed soluble forms of HLA-G, IL-6 and IL-10 as well as on immune effector cell expression of HLA-G and its cognate ILT-2 receptor in peripheral blood obtained from hospitalised and convalescent COVID-19 patients. Compared with convalescents (N = 202), circulating soluble HLA-G levels (total and vesicular-bound molecules) were significantly increased in hospitalised patients (N = 93) irrespective of the disease severity.

SARS-CoV-2-specific humoral and cellular immunity in two renal transplants and two hemodialysis patients treated with convalescent plasma.

When patients with chronic kidney disease are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) they can face two specific problems: virus-specific immune responses may be impaired and remdesivir, an antiviral drug described to shorten recovery, is contraindicated. Antiviral treatment with convalescent plasma (CP) could be an alternative treatment option. In this case report, we present two kidney transplant recipients and two hemodialysis patients who were infected with SARS-CoV-2 and received CP.

[The spread and inhibition of epileptic processes, findings with the kindling model in the cat].

The study was undertaken to describe some characteristics of subcortical brain activity during the development of an experimentally induced seizure disorder in the cat, as well as to test inhibitory effects of caudate counterstimulation. A further objective was to assess the use of closed circuit TV monitoring for the evaluation of clinical symptoms in an experimental model of limbic epilepsy. The analysis of event related potentials, spectral coherences and phases was especially suitable in order to detect a gradual lowering of the seizure threshold during the establishment of a unilateral Nucl.
