The respiratory system is constantly exposed to viral infections that are responsible for mild severe diseases. In this narrative review, we focalized the attention on syncytial virus (RSV), influenza virus, and acute syndrome-coronavirus-2 (SARS-CoV-2) infections, high morbidity mortality in last decades. We reviewed human innate adaptive immune responses airways following infection, focusing a particular population: newborns pregnant women. recent Coronavirus disease-2019 (COVID-19) pandemic has highlighted how our interest pathologies must not decrease. Furthermore, increase knowledge of infection mechanisms improve future defense strategies.

Influenza virus possesses an RNA genome of single-stranded, negative-sensed, and segmented configuration. causes acute respiratory disease, commonly known as the "flu" in humans. In some individuals, flu can lead to pneumonia distress syndrome. A (IAV) is most significant because it recurring seasonal epidemics, occasional pandemics, zoonotic outbreaks human populations, globally. The host innate immune response IAV infection plays a critical role sensing, preventing, clearing well disease pathology. Host cells sense through multiple receptors mechanisms, which culminate induction concerted antiviral creation state, inhibits clears from cells. However, antagonizes escapes many steps by different mechanisms. Herein, we review those viral This covers aspects response, i.e., (1) sensing incoming particles, (2) activation downstream signaling pathways, (3) expression interferon-stimulated genes, (4) antagonism escape.

Respiratory syncytial virus (RSV) is a significant cause of disease in the young and old. Recently, pre-fusion F protein vaccines for RSV have received food drug administration (FDA) approval to protect adults aged 60 years older; however, evaluated against typically do not elicit complete or durable protective immunity. We previously showed that an G central conserved domain (CCD) nanoparticle vaccine containing S177Q mutation (NP-S177Q) induced favorable immunogenicity RSV-neutralizing antibodies compared with vaccination alone mice. Boosting BALB/c mice NP-S177Q improved correlates protection reduced markers immunopathology following challenge. This study examined microparticle (MP) displaying CCD (MP-S177Q) adjuvanted monophosphoryl lipid A (MPLA) Our findings show MP-S177Q develop effective viral neutralization MP-WT bronchoalveolar Th1-type cytokine responses challenge vehicle-vaccinated shows rationally mutated MP safe, effective, can advance precision vaccines.

Many studies have focused on SARS-CoV-2 and Mycobacterium tuberculosis (Mtb) co-infection consequences. However, after a vaccination plan against COVID-19, the cases of severe disease death are consistently controlled, although asymptomatic mild COVID-19 still happen together with (TB) cases. Thus, in this context, we sought to compare T cell response COVID-19-non-vaccinated -vaccinated patients active exposed antigens. Flow cytometry was used analyze activation markers (i.e., CD69 CD137) cytokines (IFN-γ, TNFα, IL-17, IL-10) levels CD4+ CD8+ cells upon exposure peptides. The data obtained showed that from non-vaccinated TB present high frequency TNF-α viral challenge compared vaccinated donors. Conversely, show IL-10 spike peptide stimulus patients. No differences were observed other parameters analyzed. results suggest reduced immune balance coinfected individuals may consequences for pathogen control, necessitating further research understand its impact clinical outcomes those concurrent Mtb infections.

This responsible for one-third of pneumonia deaths the pediatric population; however, there are currently only few effective vaccines. A better understanding RSV–host relationship at molecular level may lead more management RSV-related symptoms. The fractalkine (CX3CL1) receptor (CX3CR1) co-receptor RSV expressed by airway epithelial cells diverse immune cells. G protein binds CX3CR1 via highly conserved amino acid motif (CX3C motif), which also present CX3CL1.
