Sample collection and cell counting
The plasma levels ofIL-1a, IL-1β, IL-6, TNF-α, and IL-10 were significantly higher in COVID-19 patientsthan the control group. The depicted results arerepresentative of 40 independent experiments for control group, 57independent experiments for COVID-19 patients at the first day oftreatment, and 51 independent experiments for COVID-19 patients in10 days of treatment. Data were analyzed by GraphPad Prism 6 (GraphPad Software, USA) and are expressedas the mean standard error of the mean (SEM) and mean ± standard deviation (SD).The normal distribution of data was determined by Kolmogrov–Smirnov test. The levels of erythrocyte sediment rate (ESR) and C-reactive protein (CRP) ofCOVID-19 patients were measured using the erythrocyte sedimentation rate (ESR)analyzer (Parsian Teb, Iran) and Mindray BS-800 automated biochemistry analyzer(Shenzhen Mindray Bio-Medical Electronics, China), respectively.

- All patients had pulmonary involvement and were not on treatment withdrugs influencing the immune system and antibodies production (i.e. steroids,sulfasalazine, phenytoin, and antimalarial drugs) prior to study initiation.
- The results of this study provide evidence to show that COVID-19 patients, who needto hospitalization, had some changes in the immune system during the diseaserecovery to improve and regulate immune responses.

Map of projects supported by the Recovery and Resilience Facility
Promoting entrepreneurship, competitiveness, industrialisation; improving the business environment; fostering research, development and innovation, supporting small- and medium-sized businesses. This map provides examples of reforms and investments supported by the Recovery and Resilience Facility in the different EU Member States. This will be followed by an ‘ex post evaluation’ in 2028, once the measures included in the recovery plans are fully implemented.
Other results of the currentstudy revealed that the percentage of another subset of NK cells(CD56highCD16+/− NK cells) was significantly increased atthe first day of recovery. TheCD56lowCD16+ NK cells have high expression levels ofkiller inhibitory receptors, the maturation marker (CD57), and natural andantibody-dependent cellular cytotoxicity which is mediated by releasing high levelsof perforin and enhanced killing.16,30,31 These findings suggest thatthe reduced number of CD56lowCD16+ NK cells may contribute todisease susceptibility in the early stages of disease. COVID-19, as a pandemic disease, is responsible for considerable mortality and morbidity.25 Immune system functions have fundamental role in the pathogenesis and outcomeof disease.26 Therefore, the current study focused on determining how immune system changesduring a recovery were correlated to disease severity. Thepercentages of Th1, Th2, Th17, Tregs, exhausted CD4+ T cells, exhaustedCD8+ T cells, activated CD4+ T cells, activated CD8+ T cells, and Bcells were assessed using flow cytometry (a–i) and then analyzed (j–r).The depicted results are representative of 57 independent experimentsfor COVID-19 patients at the first day of treatment, 51 independentexperiments for COVID-19 patients in 10 days of treatment, and 40independent experiments for healthy groups. The frequencies of innate immune cells in COVID-19 and control subjects.The percentages of CD56low CD16+ NK cells,CD56high CD16+/− NK cells, and monocytes werestudied by flow cytometry (a and b) and then analyzed (c–e).
- At the first day (the early recovery stage) and 10 days of initiation oftherapeutic methods (the late recovery stage), heparinized blood samples (5 ml)were obtained from patients.
- Some studies havereported that COVID-19 patients had the reduced number of Tregs in peripheral blood.22
- Moreover, Qinet al. indicated that suppressor and helper T cell percentages were lower inpatients than normal group.
- Of the 57 patients, 51 (89.48%) weredischarged from hospital and 6 (10.52%) died during the study.

RRF Regulation
The CD3+ cell population was also determined using the gating oflymphocyte population and was then used to measure the percentages of B cells(CD3− CD19+ CD22+ cells), exhausted CD4+ T cells (CD3+ CD4+ PD-1+ cells),exhausted CD8+ T cells (CD3+ CD8+ PD-1+ cells), CD56lowCD16+ NK cells (CD3− CD56lowCD16+ cells), and CD56high CD16+/− NK cells(CD3−CD56high CD16+/− cells). Afterwards, the lymphocyte population was gatedto assess the frequencies of the CD4+ cells which were used to determine thepercentages of Th1 cells (CD4+ T-bet+ IFN-γ+ cells), Th2 cells (CD4+ IL-4+GATA3+ cells), Th17 cells (CD4+ IL-17α+ RORγt+ cells), Tregs (CD4+CD127low FoxP3+ cells), and activated CD4+ T cells (CD4+ CD25+CD69+ cells). At the first day (the early recovery stage) and 10 days of initiation oftherapeutic methods (the late recovery stage), heparinized blood samples (5 ml)were obtained from patients. All patients had pulmonary involvement and were not on treatment withdrugs influencing the immune system and antibodies production (i.e. steroids,sulfasalazine, phenytoin, and antimalarial drugs) prior to study initiation.
Moreover, Qinet al. indicated that suppressor and helper T cell percentages were lower inpatients than normal group. In the next step, the adaptive immune system of COVID-19 subjects was studied after 1and 10 days of initiation of therapeutic methods. In an attempt to discover the frequency of other cells of innateimmunity, the number of monocytes was also assessed. As shown inFigure 4(a)–(d),statistically significant reduction in the levels of pro-inflammatory cytokines(IL-1α, IL-1β, IL-6, and TNF-α) in patients were observed during a recovery,with the exception of IL-1β level (P Figure 4(e),P Figure 4(f)). Having considered that severe COVID-19 is largely related to a cytokine storm,cytokine profiles of COVID patients were assessed during a recovery.
This studyinvestigated how the immune system changes were related to disease severity inCOVID-19 patients. Moreover, other data indicated thatthe levels of these cytokines were reduced during the disease recovery. PBMCs were isolated from healthy subjects and COVID-19patients and then stained with different monoclonal antibodies. To determine the situations of humoral and cellular immunity in patients withCOVID-19, the frequencies of Th1, Th2, Th17, Treg, activated CD4+T cells,activated CD8+ T cells, exhausted CD4+ T cells, exhausted CD8+ T cells, and Bcells in COVID-19 patients were investigated after 1 and 10 days of initiationof therapeutic methods. Correlations of lymphocyte numbers with the value of ESR and numbers ofTh2 cells and monocytes in COVID-19 patients. Some patients hadfatigue, mild shortness of breath, myalgia, loss of weight, smell, and taste inthe late recovery stage.
The stained cells were washedtwice with PBS and centrifuged at 300 × g for 10 min at roomtemperature. Fixation and permebilization of the cells were performed for stainingsome intracellular molecules with different antibodies according to themanufacturer’s guideline (eBiosciences, USA). The isolated cells were washed twice with phosphate buffered saline(PBS) at 300 × g for 10 min. Peripheral bloodmononuclear cells (PBMCs) were isolated from whole blood by Ficoll-Paquecentrifugation according to the manufacturer’s instructions (Lymphodex,Germany).

CD56highCD16+/− NK cells aredescribed by NKG2A, low level of perforin, and are primarily characterized bycytokine production.16,30,31 Therefore, it is likely that the changes in the frequencies oftwo subsets of NK cells during the disease recovery are protective mechanisms toeliminate the SARS-COV2 and thereby reducing inflammation occurred in the earlystages of disease. Our data revealed that the percentages of Th1, Th2, andTh17 cells were significantly lower in patients than healthy control (Figure 3(a)–(c) and (j)–(l), P Figure 3(d)–(h) and (m)–(q), P Figure 3(f), (h), (o), and (q), P Figure3(d), (e),(g), (m), (n), and (p)). The number of CD56low CD16+ NK cells in patients wassignificantly increased compared to healthy subjects. To determine the percentages of activated T cells, exhausted T cells, Th1 cells,Th2 cells, Th17 cells, Tregs, B cells, NK cells, and monocytes in peripheralblood of COVID-19 patients (the first day and 10 days of initiation oftherapeutic approaches) and healthy subjects, PBMCs were stained with differentmonoclonal antibodies or matched to isotype control IgG for 30 min at4○C. These changes may play afundamental role in reducing disease severity through regulating cytokineproductions involved in the inflammation and functions of various immune cells.Nevertheless, larger and more multicenter studies are needed to validate theseconclusions. A limitation of the study was the lack of determinationof immune system differences between alive and dead patients with COVID-19 during arecovery period.
