- Immunoregulatory Functions of the ER Stress Sensor IRE1 in Myeloid Cell BiologyAlonso Lira on 18 de October de 2025 at 10:00by inmunoadminJ Leukoc Biol. 2025 Oct 17:qiaf145. doi: 10.1093/jleuko/qiaf145. Online ahead of print. ABSTRACT Myeloid cells- including monocytes, macrophages, dendritic cells (DCs), and granulocytes constitute a versatile arm of the immune system, serving as frontline sentinels that detect and react to environmental cues and orchestrate tailored immune responses. Their ability to respond promptly to distinct threats … Read more
- Short‐Chain Fatty Acid Sodium Butyrate Suppresses Protective Humoral Immunity by Inhibiting Follicular T Helper Cell Differentiation. [[{“value”:”Bhushan Nikam,

This suboptimal humoral immunity fails to confer protection against virus infection, underscoring sodium butyrate’s potential impact on shaping GC-derived protective immunity. ABSTRACT The gut microbiome and its metabolites are critical regulators of intestinal homeostasis, … Read more
- T follicular helper cells drive functionally distinct lymphoid and lung resident germinal centres and limit allergic airway disease. Faith I Uwadiaeby inmunoadminMucosal Immunol. 2025 Oct 15:S1933-0219(25)00107-2. doi: 10.1016/j.mucimm.2025.10.005. Online ahead of print. ABSTRACT T follicular helper cells (TFH) play a central role in orchestrating antibody mediated immunity. Despite the importance of antibody responses, especially allergen-specific IgE, in allergic airway diseases (AAD) such as asthma, the precise role TFH play in AADs has remained elusive. Using a … Read more
- Three’s company: The cooperative signals behind the differentiation of Th9 cells. J Alejandra Rodriguezby inmunoadminSemin Immunol. 2025 Oct 16;80:101999. doi: 10.1016/j.smim.2025.101999. Online ahead of print. ABSTRACT T helper 9 (Th9) cells, characterized by their production of interleukin-9 (IL-9), play pivotal roles in protective immunity and inflammatory disease. Their differentiation depends on the integration of three signals: TCR engagement (Signal 1), co-stimulatory receptor activation (Signal 2), and cytokine-driven transcriptional programming … Read more
- Mycobacterium tuberculosis-specific blood immune signatures distinguish sarcoidosis from tuberculosis diseaseby inmunoadminJ Immunol. 2025 Oct 17:vkaf274. doi: 10.1093/jimmun/vkaf274. Online ahead of print. ABSTRACT Sarcoidosis is a granulomatous systemic inflammatory disease predominantly affecting the lungs. It shares histopathological, clinical, and immune features with tuberculosis (TB). There are currently no diagnostic tests to formally identify sarcoidosis; instead, there is a need first to rule out the presence of … Read more
