Summary: The immune response in the asthmatic respiratory tract is driven by CD4(+) T helper cells, especially Th2 cells. Asthma is a heterogeneous and progressive disease, with different stages of the disease course showing different immune responses. The complex immune networks in the inflammatory airway make it challenging to find a universal treatment for all asthmatics.

Summary: The review summarizes the imbalance of Th1 and Th2 cells in the tumorigenic microenvironment and the impact of IR on Th1/Th2 polarization, discussing the role in post-radiotherapy complications and highlighting that high-dose IR promotes a shift towards Th2, leading to an immunosuppressive cytokine network.

Summary: Selective differentiation of CD4+ T helper (Th) cells into specialized subsets is crucial for appropriate immune responses. While canonical Th-cell lineages are well understood, the transcriptional architecture of hybrid phenotypes remains unclear. This study explored the transcriptome of Th-cell differentiation, revealing an early bifurcation point in gene expression programs. Hybrid Th1/2 cells showed mixed effects from Th1 and Th2 cells for a minority of genes, while others followed a Th1 and Th2 cell-independent transcriptional program. These findings emphasize the importance of longitudinal data for characterizing cellular phenotypes.

Summary: This study aimed to characterize the differentiations of naive Th cells stimulated with different doses of Staphylococcus aureus enterotoxin B (SEB). The results showed that the balance of Th1/Th2 could be dominated by the doses of SEB stimulation, with a higher dose inducing more Th1 cells and a lower Th2/Th1 ratio. This finding complements the existing knowledge about SEB as a superantigen and has implications for managing S. aureus colonization and SEB contamination in food.

Summary: This study investigated the role of selenoproteins in Sch B-induced autophagy and Th1/Th2 imbalance in Hepa1-6 cells. The results showed that Sch B inhibited cell proliferation and induced autophagy in Hepa1-6 cells. Sch B treatment also led to the accumulation of ROS and Th1/Th2 immune imbalance. The majority of selenoproteins were found to be involved in these processes.

Summary: The study found that GMK achieves a similar effect as dexamethasone in controlling symptoms of allergic asthma and inhibiting inflammation, reconstructs the immune balance of Th1/Th2 and Treg/Th17 cells, and impacts asthma treatment by altering gut microbiota. Metabolome results reveal specific substances associated with Th1/Th2 and Treg/Th17 cell balance.

Summary: CD4(+) T cells are crucial in controlling and clearing infections as a major arm of cellular immune response. They are heterogeneous and can be divided into six main lineages with distinct profiles. Recent advances in structural biology have allowed for a detailed understanding of the molecular mechanisms driving CD4(+) T cell recognition of pathogens.

Summary: Asthma is an inflammatory disease in which Th2 differentiation and dendritic cells (DCs) play important roles. Highly expressed March1 can promote Th2 differentiation induced by DCs through facilitating OX40L expression and contribute to the development of asthma. These findings might provide new insights into the treatment of asthma.

Summary: The classification of duckweeds as a subfamily of the expanded family Araceae rather than a separate family has sparked debates in the field of botanical taxonomy. The proposal to restore the subfamily Orontioideae to family status as Orontiaceae aims to maintain stability and utility in plant classification.

Summary: Control of malaria requires Th1 cells with IL-10 to mitigate inflammation, but IL-10+Tr1 cells can also promote parasite persistence or impair immunity. Molecular and phenotypic signatures distinguish IL-10-Th1 cells from IL-10+Tr1 cells in malaria-infected individuals and mice, and a conserved Tr1 cell signature is found in patients with malaria, dengue, and graft-versus-host disease.

Summary: MT1-MMP plays a crucial role in promoting cancer cell invasion. In this study, three kinesin superfamily motor proteins (KIFs), KIF3A, KIF13A, and KIF9, were identified to be involved in the transport of MT1-MMP-containing vesicles. Knockdown of KIF3A and KIF13A inhibited MT1-MMP-dependent collagen degradation and invasion, while knockdown of KIF9 increased collagen degradation and invasion. Live-cell imaging analyses revealed the coordinated transport of MT1-MMP-containing vesicles by KIF3A and KIF13A from the trans-Golgi to endosomes, and the transport of vesicles from endosomes to the plasma membrane by KIF13A alone. This study uncovers a unique interplay between three KIFs in regulating the leading edge localization of MT1-MMP and MT1-MMP-dependent cancer cell invasion.

Summary: This study reveals that the density of cognate peptide-MHCII (pMHCII) plays a quantitative role in instructing selection and cell fate decisions. By using differential delivery of OVA peptides to GC B cells based on DEC205 allelic copy number, the study shows that an increase in antigen uptake leads to proportional TFH cell help and B cell expansion. The results are further validated by the establishment of a caged OVA peptide. Differential CD40 signaling is found to be both necessary and sufficient for mediating differences in B cell expansion. The study also distinguishes the roles of TFH cells in expansion versus differentiation.

Summary: This paper presents a protocol for using Bead-Supported Lipid Bilayers (BSLBs) as antigen-presenting cell (APC) mimetics to capture and analyze trans-synaptic particles. The protocol also includes absolute measurements of protein densities on cell surfaces, reconstitution of BSLBs with physiological levels, and a flow cytometry procedure for tracking synaptic particle release by T cells. The protocol can be adapted to study the effects of various factors on T cell effector output.

Summary: While immune checkpoint blockade has revolutionized cancer treatment, the majority of patients do not benefit from it. Various efforts have been made to interrogate the immune system using different biospecimens, technologies, and disciplines, but consistent biomarkers of response have remained elusive. Pharmacokinetics studies, however, provide critical information and may reveal useful biomarkers.

Summary: Ligation of TCR to pMHC induces TCR ubiquitination and either internalization by T cell or release in extracellular vesicles. Clathrin-mediated ectocytosis facilitates the release of TCR, while clathrin-mediated trans-endocytosis enables the uptake of pMHC-TCR conjugates from the APC.

Summary: Clarke and colleagues discovered that germinal center B cells have dynamic mitochondria regulated by the transcription factor TFAM. TFAM helps the B cells enter the germinal center reaction by modulating cellular motility. Understanding this mechanism is important as germinal center B cells undergo rapid proliferation in a hypoxic microenvironment.

Summary: Chemoimmunotherapy with anti-PD-1/L1 and cytotoxic chemotherapy is a promising treatment for triple-negative breast cancer, but further research is needed to determine the optimal chemotherapy regimen and biomarkers for patient selection. This study investigated the safety and efficacy of pembrolizumab in combination with paclitaxel or capecitabine, and found that both regimens were safe and clinically active.

Summary: Pancreatic ductal adenocarcinoma (PDAC) is a deadly cancer type with a low 5-year survival rate of less than 8% due to its complex biology. Understanding the functional dynamics of T cells in the PDAC microenvironment is crucial for developing alternative therapeutic strategies, as PDAC is resistant to immunotherapy.
