lymph nodespathologysplenomegalyThe immune system has evolved to deal with pathogens. Analysing what happens during the course of infectious processes provides insights into the limits of lymphocyte homeostasis. Virus infections greatly alter normal T- and B-cell prevalence and localization patterns. Any ...
1A). These aAPCs mimic the physiological presentation of viral antigens to CD8+ T cells by dendritic cells that occurs in local draining lymph nodes during viral infection, and the coating of the particles with anti-CD28 antibodies provides the necessary co-stimulatory signals that are critically ...
lymph nodes, spleen, and female reproductive tract (Fig.5A, Supplementary Figs.8Aand9A). CD8+T cell responses were higher in animals that were chronically infected prior to the initiation of ART, most likely reflecting the short duration of virus replication in animals in the Early ART cohort ...

(BM) and undergo a complex developmental process to acquire their effector functions. However, emerging evidence has suggested that their development is not narrow to the BM but also occurs in secondary lymphoid tissues likes spleen, tonsils, and lymph nodes [14]. NK cell development begins with...
However, cART does not cure HIV infection as virus persists in cellular and anatomical reservoirs, from which the virus generally rebounds soon after cART cessation. One major anatomical reservoir are lymph node (LN) follicles, where HIV persists through replication in follicular helper T cells and...
Although augmented interferon production was detected in the draining Lymph nodes (dLNs) in Treg-deprived mice, it was profoundly reduced at the infection site. This was associated with a delay in the arrival of natural killer cells, dendritic cells, and T cells to the site of infection and ...
The mRNA vaccine technology was developed rapidly during the global pandemic of COVID-19. The crucial role of the COVID-19 mRNA vaccine in preventing viral infection also have been beneficial to the exploration and application of other viral mRNA vaccine
lymph nodes and at the site of infection, while blockade of β-adrenergic receptors restored activation of virus-specific cytotoxic T cell responses (Dobbs, Vasquez, Glaser, & Sheridan, 1993). Thus, our approach to studying neuroendocrine–immune interactions during viral infection revealed that both...
, the most efficient cells for stimulating an immune response (leucocyte dendritic cells) are not present in the healthy CNS; and third, there is no specialized lymphatic drainage from the CNS to lymph nodes to enable the immune system to be quickly informed of the presence of an infection. ...
