Interventions
DIAGNOSTIC_TEST

Cytokines measurement

Quantification of plasma cytokine levels of human GM-CSF, IFN-α, IFN-γ, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-12p70, IL-17A, and TNF-α using multiplex technol-ogy (quantitative measure).

DIAGNOSTIC_TEST

Cellular response

SARS-CoV-2 peptides (Prot-S, Pros-N and Port-M) will be used to activate CD4 and CD8 T cells. Cytokines released, such as IFNg, TNFa, IL4, IL17A, and IL2, from each cell subset will be measured by flow cytometry (quantitative measure).

DIAGNOSTIC_TEST

TLRs activation measurement

After specific cell activation through TLR7/8 receptors, such as resiquimod, ORN R-0002, ORN R-0006, ORN R-1263, ORN R-2336, and controls as Poly (I:C), the release of IFNa, IFNg, TNFa, IL12, and IL6 will be analyzed (quantitative measure).

DIAGNOSTIC_TEST

KIR phenotype evaluation

Characterization of the presence of 14 genes plus 2 pseudogenes of KIR gene family (qualitative genotyping) by PCR, mRNA expression profiling (quantitative measures) by RT-PCR, and phenotyping of human NK cells analyzing different KIR receptors (quantitative measure) by flow cytometry, will be analyzed.
