#GuillainBarrésyndrome (GBS) can be triggered by several viral and bacterial pathogens that induce peripheral nerve damage through immune-mediated mechanisms such as molecular mimicry link.springer.com/article/10.1... link.springer.com/chapter/10.1... www.researchgate.net/publication/...
Representation of molecular mimicry, pathophysiological mechanism of GBS. The pathophysiology of GBS is evidenced by the mechanism of molecular mimicry, in which the virus shares epitopes common to neuron components, such as the myelin sheath and axonal lining. Thus, direct virus infection triggers the activation of the immune system and APC precursor cells, which differentiate into T and B lymphocytes. Also, the viral epitope is recognized by the B lymphocyte and the T lymphocyte releases isoleucine such as IL-6 and interleukin 4 (IL-4), in addition to cytokines such as TNF-α and interferon-gamma (IFN-γ) for macrophage activation, triggering local inflammation that can be exacerbated. Thus, there is the production of antibodies (ANTI-GM1) to attack the virus, however, by sharing epitopes, these antibodies also attack components of the neuron. The recruitment of more macrophages increases inflammation, as well as the performance of the microglia that release cytokines such as IFN-γ and interleukin 1 beta (IL-1β). Finally, the neuron is in hyperinflammation and operates with its reduced functionality or loses it definitively, being able to suffer cell death and causing irreversible damage to the patient with this syndrome

🧬The virological profile of PJ.2.1 is characterized by an exceptional binding strength to host cell receptors coupled with a unique structural vulnerability to antibodies
Virological Profile & Spike Dynamics of PJ.2.1Virological, epidemiological, and antigenic characterization of the the SARS-CoV-2 saltation variant PJ.2.1
(A) Schematic evolutionary pathway and spike glycoprotein mutational profile of SARS-CoV-2 saltation variant PJ.2.1. PJ.2.1 (Ontario) and PJ.2.1 (New York) represent distinct clinical isolates.
(B) Global geographic distribution of SARS-CoV-2 variant PJ.2.1. Coral shading highlights countries with detected cases. Labels indicate geographic location, sequence counts, corresponding isolate (PJ.2.1_ON or PJ.2.1_NY), and earliest collection dates (month/year), using data retrieved from GISAID and NCBI GenBank.
(C) Soluble human ACE2 neutralization against KP.3.1.1, MC.10.1, NB.1.8.1, PQ.16.1.1, XFG, BA.3.2.2, and PJ.2.1_ON pseudoviruses. Columns and numeric values indicate geometric mean half-maximal inhibitory concentration (IC50, μg/mL) values, with scatter points representing independent technical replicates. Statistical significance was evaluated using a two-tailed t test on log-transformed IC50 values.
(D) Surface plasmon resonance (SPR) measurement of human ACE2 (hACE2) binding affinities for NB.1.8.1, XFG, BA.3.2.2, and PJ.2.1_ON spike trimers. Bar heights and embedded values indicate geometric mean dissociation constants (KD, nM), with scatter points denoting individual technical replicates. Statistical significance was evaluated using two-tailed t test on log-transformed KD values.
(E) Antigenic cartography based on serum NT50 titers from mice immunized with two doses of spike mRNA vaccines against indicated variants.
(F) Plasma neutralization titers against MC.10.1, PQ.16.1.1, XFG, BA.3.2.2, and PJ.2.1_ON pseudoviruses in Omicron-primed (n=12) and Wuhan-Hu-1-primed (n=36) cohorts. Solid horizontal lines and numerical values designate geometric mean titers (NT50), with individual connected dots indicating paired plasma samples. The horizontal dashed line marks the limit of detection (NT50=10). Statistical comparisons, fold changes relative to PJ.2.1_ON,

#Medsky🧪 #Neurosky #publichealth In a 2025 @sciimmunology.bsky.social Review, The study discussed how interactions between the nervous and immune systems could impact neurological disorders and allergy-related behaviors like food avoidance. www.science.org/doi/10.1126/...
Fig. 1. Interactions between the nervous system and type 2 immunity occur across multiple organs depending on the context of allergic triggers or injury.
The nervous system comprises the CNS and associated sensory nerves (blue) and the autonomic nervous system, which includes sympathetic and parasympathetic nerves (red) and the ENS (purple). The immune system is composed of cells that span the entire body. This includes the meningiocranial immune system, which comprises immune cells important for neural development, brain repair, and brain border protection. Repeated exposure to allergens at mucosal sites (for example, lung, skin, and gut) can trigger local type 2 immunity. Type 2 immune cells signal to neurons across the periphery and brain through cytokines, whereas neurons signal to immune cells via neurotransmitters and neuropeptides. This is not an exhaustive list of cellular players, given that other tissue resident cells (e.g., fibroblasts and glial cells) may also respond to these signals.
