Myeloproliferative neoplasms ( MPN ) is a class of clonal hematopoietic stem cell disease. Studies found that the JAK-STAT signaling pathway is closely related to the pathogenesis of MPN. The lymphocyte-specific adaptor protein (LNK) gene negatively regulates Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling and may play an important role in the pathogenesis of MPN. Especially in JAK2 mutation-negative MPN, LNK gene specific mutations may be the key to cause MPN subtypes. Certain single nucleotide polymorphism of LNK gene regulation of hematopoietic cells in different directions may also be important influence factors of MPN performance for different subtypes. LNK gene functional changes lead to abnormal activation of the JAK-STAT signaling pathway, and may be a new mechanism of MPN. In this review, the role of LNK gene in MPN pathogenesis is briefly summarized.

Article Synopsis
- * Understanding inherited traits is essential for making decisions regarding allogeneic hematopoietic cell transplants (allo-HCT) and choosing suitable donors.
- * The case of a 49-year-old woman with JAK2 V617F-positive primary myelofibrosis (PMF) illustrates the significance of genetic findings, including a variant in the SH2B3 gene, in clinical management and genetic counseling for transplant options.

Background: The COVID-19 pandemic has spurred significant endeavors to devise treatments to combat SARS-CoV-2. A limited array of small-molecule antiviral drugs, specifically monoclonal antibodies and interferon therapy, have been sanctioned to treat COVID-19. These treatments typically necessitate administration within ten days of symptom onset.

Background: Recent evidence highlights the pivotal role of natural killer (NK) cells in allograft rejection.
Methods: We explored associations of missing self and gene polymorphisms determining the phenotype and/or functionality of NK cells with microvascular inflammation (MVI) in a single-center cohort of 507 consecutive kidney transplant recipients. Patients were genotyped for killer cell Ig-like receptors and polymorphisms in 4 selected genes (FCGR3AV/F158 [rs396991], KLRC2wt/del, KLRK1HNK/LNK [rs1049174], and rs9916629-C/T).

The germinal centers (GCs) are structure found within secondary lymphoid organs and are important for the antibody-producing response against foreign antigens. In GCs, antigen-specific B cells proliferate intensely, inducing immunoglobulin class switching. Recent studies have shown that GCs are also an important site for class switching to IgE, which is implicated in allergy.

The impact of rising global temperatures on crop yields is a serious concern, and the development of heat-resistant crop varieties is crucial for mitigating the effects of climate change on agriculture. To achieve this, a better understanding of the molecular basis of the thermal responses of plants is necessary. The circadian clock plays a central role in modulating plant biology in synchrony with environmental changes, including temperature fluctuations.
