Aims: To understand the characteristics of combined immunodeficiency disorders that affect cellular and humoral immunity (CID) in the Arabian Peninsula.
Methods: Retrospective study of 236 patients with CID from the region were enrolled from 2004 to 2022.
Results: 236 patients were included with a majority being profound CID. Among patients with a family history of CID, the ages at onset and diagnosis, and the delay in diagnosis were lower compared to those with no family history of CID, but this did not affect time to transplant. HSCT was performed for 51.27% of the patients with median time from diagnosis to HSCT of 6.36 months. On multivariate analysis, patients who underwent early transplant had increased odds of having CD3 count ≤1000 cell/μl, diagnosed by screening or erythroderma.
Conclusion: There is a delay in diagnosis and treatment of CID in our region. Establishing newborn screening programs and HSCT units in our region are the urgent need.

MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.

Contagious bovine pleuropneumonia (CBPP), caused by subsp. (Mmm), is a devastating cattle disease with high morbidity and mortality, threatening cattle productivity in Sub-Saharan Africa and potentially in parts of Asia. Cross-border livestock trade increases the risk of CBPP introduction or reintroduction.

B cell tolerance is critical for preventing autoimmunity, yet the mechanisms by which B cells discriminate self from non-self antigens remain incompletely understood. While early findings emphasize the role of classical antigen-mediated BCR signaling strength by varying antigen formats, emerging evidence highlights the importance of mechanical cues during antigen recognition. This review explores how mechanosensitive ion channels, particularly Piezo1, contribute to B cell activation and tolerance by integrating physical forces at the immune synapse.

Avian influenza virus infections pose a potential pandemic threat. The currently licensed vaccines have inherent limitations, emphasizing the urgent need for improved influenza vaccines. Here, we developed a novel hemagglutinin (HA) virus-like particle (VLP) vaccine candidate through the baculovirus expression vector system (BEVS).

Entomopathogenic fungi can precisely inhibit the cellular and humoral immune responses of host insects by secreting effector proteins, allowing them to overcome the innate immune barriers of their hosts. Nodule formation is an immune response primarily mediated by insect hemocytes, which can rapidly and efficiently capture invading pathogenic fungi in the hemocoel. However, the molecular mechanisms by which fungi inhibit insect nodule formation through the secretion of effector proteins remain unclear.
