Humoral Immunity vs. Salmonella

Frontiers in Immunology, 2020
In primary infection with Salmonella, it has been reported—without consideration of Salmonella's functions—that humoral immunity plays no role in the clearance of bacteria.

Red blood cell alloimmunization in pregnancy: A 10-year single-center study [PDF]

Vojnosanitetski Pregled, 2022
Background/Aim. Pregnancy-induced red blood cell (RBC) alloimmunization is important not only because of the possible negative effects on subsequent pregnancy outcomes in case the fetus carries the antigen but also because of the optimal trans-fusion ...

Structural insights into the biological functions of the long pentraxin PTX3

Frontiers in Immunology, 2023
Soluble pattern recognition molecules (PRMs) are a heterogenous group of proteins that recognize pathogen- and danger-associated molecular patterns (PAMPs and DAMPs, respectively), and cooperate with cell-borne receptors in the orchestration of innate ...

Broadly neutralizing anti-HIV-1 antibodies tether viral particles at the surface of infected cells

Nature Communications, 2022
Broadly neutralizing antibodies (bNAbs) neutralize HIV-1 and exert Fc-dependent activities against infected cells. Here, Dufloo et al. show that bNAbs also block HIV-1 release by trapping viral particles at the surface of infected cells.

Diverging humoral and cellular immune responses due to Omicron—a national study from the Faroe Islands

Microbiology Spectrum, 2023
Immunity following infection and vaccination with the SARS-CoV-2 Omicron variant is poorly understood. The aim was to investigate immunity assessed with antibody response, neutralizing antibodies (NAbs), and IFN-γ release under different scenarios: in ...

The immune response to the novel coronavirus infection [PDF]

Клиническая практика, 2021
This review summarizes the current knowledge on the humoral and T-cell immunity to the novel coronavirus infection. A special attention is paid to the viral proteins that induce production of antibodies, different types of immunoglobulins and their role ...

Antibody Neutralization of HIV-1 Crossing the Blood-Brain Barrier

mBio, 2020
HIV-1 can cross the blood-brain barrier (BBB) to penetrate the brain and infect target cells, causing neurocognitive disorders as a result of neuroinflammation and brain damage.

The dysfunction of Tfh cells promotes pediatric recurrent respiratory tract infections development by interfering humoral immune responses

Heliyon, 2023
Recurrent respiratory tract infections (RRTIs) are one of the most common pediatric diseases. Although the pathogenesis of pediatric RRTIs remains unknown, ineffective B cell-dominated humoral immunity has been considered as the core mechanism.

Effectiveness and Durability of mRNA Vaccine-Induced SARS-CoV-2-Specific Humoral and Cellular Immunity in Severe Asthma Patients on Biological Therapy

Frontiers in Immunology, 2022
Coronavirus disease 2019 (COVID-19) vaccines effectively elicit humoral and cellular immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in healthy populations. This immunity decreases several months after vaccination.

Kinetics of severe acute respiratory syndrome coronavirus 2 infection antibody responses

Frontiers in Immunology, 2022
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly throughout the world, causing severe morbidity and mortality. Since the first reports of Coronavirus disease 2019 (COVID-19) in late 2019, research on the characteristics of ...
