ABSTRACT Pinctada fucata martensii is an economically important mollusk in aquaculture, known for marine pearl production. The inflammatory response during the transplantation process was a key factor affecting pearl yield. Our previous studies have revealed the critical role of nicotinic acetylcholine receptors (nAChRs) from … Read more

J Immunol. 2025 Oct 13:vkaf282. doi: 10.1093/jimmun/vkaf282. Online ahead of print. ABSTRACT B cells have been shown to be phagocytic under some circumstances. However, the phagocytic capacity of different B-cell subsets and how this is linked to antigen (Ag) presentation or other functions has not been characterized. To address this, we developed 2-µm phagocytic Ag-conjugated … Read more

J Immunol. 2025 Oct 12:vkaf249. doi: 10.1093/jimmun/vkaf249. Online ahead of print. ABSTRACT Inflammation has enduring impacts on organismal immunity. However, the precise mechanisms by which tissue-restricted inflammation conditions systemic responses are poorly understood. Here, we leveraged a highly compartmentalized model of skin inflammation and identified a surprising type I interferon (IFN)-mediated activation of hematopoietic stem/progenitor … Read more

J Immunol. 2025 Oct 10:vkaf268. doi: 10.1093/jimmun/vkaf268. Online ahead of print. ABSTRACT Tuberculosis (TB) is a major global health threat. Deep knowledge of the immune responses against Mycobacterium tuberculosis (Mtb) is crucial for developing effective interventions. Data support that both innate and adaptive CD8+ lymphocytes contribute to protective immunity in Mtb infections, commonly attributed to … Read more

J Immunol. 2025 Oct 10:vkaf214. doi: 10.1093/jimmun/vkaf214. Online ahead of print. ABSTRACT Memory CD8+ T cells are essential for long-term protective immunity. Here, we show that activation of p38 MAPK during the primary response of CD8+ T cells orchestrates a delicate balance between the formation of short-lived effector cells and memory precursor effector cells. p38αfl/flp38βfl/flGzmBcre/- … Read more

J Immunol. 2025 Oct 10:vkaf272. doi: 10.1093/jimmun/vkaf272. Online ahead of print. ABSTRACT Sepsis followed by multiple organ failure is a leading cause of death in noncoronary intensive care units. While the NLRC4 inflammasome has been shown to play a crucial role in the innate immune response, the role of NLRC4 in sepsis remains unclear. Here, … Read more

J Immunol. 2025 Oct 8:vkaf123. doi: 10.1093/jimmun/vkaf123. Online ahead of print. ABSTRACT Vaccination strategies and correlates of protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have predominantly focused on the spike (S) protein and neutralizing antibodies. However, the rapid emergence of SARS-CoV-2 variants has reduced the effectiveness of spike-based vaccines and monoclonal antibodies. It … Read more

J Immunol. 2025 Oct 8:vkaf154. doi: 10.1093/jimmun/vkaf154. Online ahead of print. ABSTRACT Spring viremia of carp virus (SVCV) represents a significant threat to cyprinids, particularly common carp (Cyprinus carpio). The disease caused by this virus is characterized by tissue necrosis and petechial hemorrhages. However, the pathogenesis of SVCV infection remains poorly understood. Pyroptosis, a recently … Read more

ABSTRACT Pneumocystis jirovecii pneumonia remains a significant cause of mortality and morbidity in immunocompromised populations worldwide. Mortality rates range from 5% to 30% in HIV-positive individuals and 4% to 76% in those without HIV. Recognizing its public health impact, the World Health Organization (WHO) … Read more
