Monoclonal antibodies have emerged as highly specific biologics, increasingly recognized as the gold standard across multiple therapeutic areas.&nbsp;<\/p>\n\n\n\n<p>At Immune Biosolutions, we have immunized B-cell libraries for a variety of targets that enable fast and efficient discovery pipelines, accelerating the path from target to therapeutic candidate.&nbsp;<\/p>\n\n\n\n<p>In addition, our team has built strong expertise in bi-specific antibody engineering, allowing us to synergize signaling pathway modulation and unlock greater therapeutic potential. Here\u2019s a few targets of interest:&nbsp;<\/p>\n\n\n\n<p><strong>PD-1 and PD-L1<\/strong>&nbsp;<\/p>\n\n\n\n<p>The Programmed cell death protein 1 (PD-1, CD279) and its ligand programmed death-ligand 1 (PD-L1, CD274) have become cornerstone targets in immuno-oncology. Many cancer cells exploit this receptor\u2013ligand interaction to suppress immune surveillance and escape recognition by T cells. By blocking the PD-1\/PD-L1 pathway, therapies can reinvigorate antitumor immunity, an approach that has already transformed cancer treatment and continues to expand into new indications.&nbsp;<\/p>\n\n\n\n<p><strong>CCR8<\/strong>&nbsp;<\/p>\n\n\n\n<p>C-C chemokine receptor type 8 (CCR8) has emerged as an attractive immuno-oncology target because of its selective and high expression on tumor-resident regulatory T cells (Tregs). Monoclonal antibodies are the modality of choice for this pathway, offering both high specificity and the ability to induce antibody-dependent cellular cytotoxicity (ADCC). By simultaneously depleting immunosuppressive Tregs and activating effector responses through ADCC, CCR8-directed therapies aim to remodel the tumor microenvironment into a pro-inflammatory, anti-tumor state.&nbsp;<\/p>\n\n\n\n<p><strong>TGF-\u03b2<\/strong>&nbsp;<\/p>\n\n\n\n<p>Transforming Growth Factor Beta (TGF-\u03b2) is an attractive therapeutic target because of its involvement in a wide range of biological pathways. However, this pleiotropy also makes it a challenging node to drug, where balance and specificity are critical to maximize efficacy while minimizing off-target effects. Among available modalities, recombinant antibodies remain the most compelling due to their high specificity and long half-life. In particular, bi-specific antibody formats are emerging as powerful tools for fine-tune signaling modulation and to achieve more precise therapeutic outcomes.&nbsp;<\/p>\n\n\n\n<p><strong>IL-1\u03b2<\/strong><\/p>\n\n\n\n<p>Interleukin-1 Beta (IL-1\u03b2) is a pleiotropic cytokine with a central role in diverse inflammatory and tumor-promoting pathways. While this broad activity makes it an attractive target, it also demands careful modulation to avoid unwanted immunosuppression. Bi-specific antibody engineering offers a promising strategy to narrow targeting toward disease-driving contexts, improving selectivity and maximizing therapeutic benefit.\u00a0<\/p>\n\n\n\n<p>For a complete list of available pre-immunized libraries, <a href=\"mai&#108;&#116;&#111;&#x3a;&#x69;&#x6e;&#x66;&#x6f;&#x40;ibi&#111;&#115;&#111;&#108;&#x75;&#x74;&#x69;&#x6f;&#x6e;&#x73;&#46;co&#109;\" target=\"_blank\" rel=\"noreferrer noopener\">contact us<\/a> or visit our <a href=\"https:\/\/immunebiosolutions.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">website<\/a>.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The past few years have brought a wave of promising new targets for the treatment of cancer and inflammatory diseases&#8230;.<\/p>\n","protected":false},"author":35,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[55],"tags":[],"class_list":["post-4018","post","type-post","status-publish","format-standard","hentry","category-article"],"acf":[],"taxonomy_info":{"category":[{"value":55,"label":"Article"}]},"featured_image_src_large":false,"author_info":{"display_name":"Laurence Tessier","author_link":"https:\/\/immunebiosolutions.com\/en\/author\/ltessieribiosolutions-com\/"},"comment_info":0,"category_info":[{"term_id":55,"name":"Article","slug":"article","term_group":0,"term_taxonomy_id":55,"taxonomy":"category","description":"","parent":0,"count":2,"filter":"raw","cat_ID":55,"category_count":2,"category_description":"","cat_name":"Article","category_nicename":"article","category_parent":0}],"tag_info":false,"_links":{"self":[{"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/posts\/4018","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/users\/35"}],"replies":[{"embeddable":true,"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/comments?post=4018"}],"version-history":[{"count":3,"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/posts\/4018\/revisions"}],"predecessor-version":[{"id":4025,"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/posts\/4018\/revisions\/4025"}],"wp:attachment":[{"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/media?parent=4018"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/categories?post=4018"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/immunebiosolutions.com\/en\/wp-json\/wp\/v2\/tags?post=4018"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
